honda accord 98 V6-L exhaust

[Dray_Templar]

Hi Members

I have been talking to a mate (he works for an exhaust centre) about upgrading my exhaust system. Apart from the normal Exhaust tubing that he will make up for me what other parts will i need to purchase to make the upgrade worth while, eg high flow cat (not sure about that just heard it somewhere).

I can't decide what size to go for, becasue I'm not sure at this point if i will supercharge/turbo it at this point. is there an exhust size that would be suitible for both? NA and turbo/superchager so that i would not have to replace it again later if i decided to turbo/superchager.

was thinking around the 2 and 3/4. but would like to hear other peoples ideas and explanations on for and against.

Thanks again, all ideas would be very helpfull.

oh no i think i'm turning into a ricer, i got LED Under Body neon's :P least there not hooked up yet :P

Well, if you're NA at the moment (& plan to stay that way) then I would suggest 2.25" or 2.5" piping, and to make it worthwhile I would suggest high flow cat (like you said), headers and CAI. This is probably step one, then next step is to go cam gears, pulleys, VAFC and tune (I'm sure I'm forgetting other things here). BUT, if you're planning on turbo/supercharge in the near future, then a suitable 2.75" or 3"(depending on how much you wanna boost) and definetly a highflow cat. BUT, from what I've experienced, while the car is NA, the larger diameter "zorst" piping leads to a drop in available low end torque. To some people this is acceptable but others have complained about it's effect in city driving. Either way you go, happy modding and do post pics.

OH....almost forgot: Whatever you do, don't forget that your tranny is the weakest part and will most likely die the moment you slap on some high power mods. So, think it through carefully especially if this is your daily-driver.

[poid]

why not wait until you have decided exactly what you will do?

2 3/4" is a bit too big IMO if you are going to keep it NA, i wouldnt go any higher than 2.5". You'd probably find that a well built 2.25" exhaust with properly designed headers and high flow cat/muffler would be a good size in the end, as going oversized in an NA application hurts exhaust velocity and therefore power. Of course a properly designed setup wouldnt be cheap, and i think most exhaust places wouldnt be able to do it these days. Which is why people tend to make more power going a step up (but less power than they *could* be making)

[accordingly flash]

i was looking at supercharging my 6th gen v6 but was advised that the tranny computer cant read boost,so was going to be a mamoth task...

as for the zorst,i went to a custom zorst place and was told not to bother,as the stock honda stuff flows well and wotever i did would prolly sound over the top...
let me know how ya go but...

Wow, never knew there wer so many fellow 1998-98 Accord owners!

damn....

Guys, I've checked...with a powerful 3.0 V6 DOHC engine...not worth applying turbo!! with our cars...when VTEC kicks in, we can go faster than a 4 cyclinder with turbo on the fly so why get turbo for....my car is a v6 LUX so it's suppose to be lux car...just rice it up! spend your money on other things like investments....a good turbo will cost you over 5K's!

[Dray_Templar]

I no what you mean but i seem to of caught the performance bug lol, my best mate has a Nissan ET Turbo, this thing flies. will post a link soon, so you can see what i'm up against.

i no that im never going to beat him lol, i got the wrong type of car, but don't wanna be lapped when we take it on the track (we live 30km from Winton Motor Race way). The other think is seems not to many people have done it, it would be one huge way to stand out from the crowd. Was going to wait till i could get a Supra to do all my car modding but falling in love with the honda and feel there is so much more i can do, and been totally diffrent to everyone else. Just abit more work and money than you would need to do a supra thow lol. arh well.

Anyway alot more looking into this needs to be done before i decide, was just hoping that maybe there may of been a exhaust size that would suite NA/ and turbo/supercharger so i would not have to install a new one when/if i decide to go supercharger/turbo. (to go with the supercharger or the tubo will have to be a diffrent topic when/if i decide to go down that track)

also read and article in a hot4's mag, about people being able to build custom manual box's from other cars and custom parts. (would be intresting to look at if i ever got rich lol ).

thanks everyone for you great responces and recomendations.

P.S Honda Enthusiast from memory our v6-L's produce about 147Kw, and weigh about 1.4 tonne. alot of 4's are going to annilate us even when there stock.

P.P.S

Supercharger: Addtional 42-48 wheel horsepower

when VTEC kicks in, we can go faster than a 4 cyclinder with turbo on the fly so why get turbo for....


LOLOLOL

Oh ... My ... God

That just made my day

Thanks buddy

[B|ade]

I've also heard with a "powerful" 3.0 V6 DOHC engine I can beat Lancers and Mirages too ... Definately no need to modify it nemore.

I've also heard that with some stickers I'll be beating any turbo car ever made.

very interesting..........? so my little 1.5 4cyl turbo can beat a brand new clubby or gt-p falcon, but will have no chance of beating a Honda Accord v6-L. Ok Ok, you might have me on the start line coz i will have a lot of trouble trying to get traction but soon as i get going or turbo on the fly?! you can bet i'll be flying past at a rapid rate! But you did make me lough!!!!! Get some stickers!

Anyway, Dray, you should think about what you want your car for, i'd recommend 2.5 tops for it naturally and 3 up for forced induction. If you go natural you don't want to go too big otherwise you'll lose backpressure/power. If you go forced induction, the bigger the better, you don't want backpressure, you want flow and lots of it! Have a think about it! On the other hand it would be different having it supercharged or turboed, but would end up costly! L8TR

P.S-And my car doesn't look sweet. but thanks anyway.

[poid]

If you go natural you don't want to go too big otherwise you'll lose backpressure/power.

just one point (its one of the big modifying myths around today). In any exhaust, you dont want any backpressure at all. The reason that piping diameter is smaller for NA cars vs a turbo car of the same engine size is that the NA car needs to keep the exhaust velocity as high as possible to help the flow in and out of the cylinders. For a boosted car you have the boosted air coming through and forcing the exhaust out in any case so velocity isnt an issue.

velocity means smaller piping, but avoiding backpressure means larger piping. So there is obviously a compromise there to be made, and you'll lose power if its too big or too small (and also if the design sucks).

lol Mate seen your 2 rides before this one, and in comparson, your current one is sweet ;)

Anyway's i guess it Just comes down to $$$, if i had the momey i would turbo or supercharge tommorow! lol
Guess i might just have to start saving :(

P.S hurry up and get it on the road and come cruizing bro.

[Shaggin Wagon]

alot of ppl dont know that piping isnt a performance issue, u dont want back pressure, the onli reason u need some back pressure is so u dont overflow and waste fuel.... if the exhaust is too big in a n/a car the mixture will fill the cylinder then start to fill the exhaust which is a waste as it doesnt burn......
goodluck boosting the v6 motor man, it would be hard enough getting it to work let alone getting sumthing to run the fuel side.

[Dray_Templar]

rgr that, so basically i have to decide weather i'm going to turbo or not, then do the upgrade.

cheers all

[Dray_Templar]

Was getting borred on Sunday, so thought what the hell, take the intake filter out and the top off it and go for a real small spin and see what it's like... and omfg .. :) i love the intake noice you get sounds so farking sweet. Now i have to look into setting up pod filter, hopefull i still get some of the intake sound with the pod filter :)

ok the long term plan for my car is now Supercharger :)... so will be looking towards 3" exhuast, damn this is going to cost me a fortune by the time it's done, but least it will be one of a kind.

[Vinnie]

u took ur car for a drive with no air filter? do that again and u wont have a working engine to strap a blower onto... good luck with ur modding tho :)

;) only went about 500meters.

[SiReal]

thats nuts dude.. .yeah induction noise is loud an very meaty. had a metal mesh pod on for a bit (crap as), but it was sooo loud, then had a paper based one (simota), vtec wasnt as loud but at least i knew it was doing a better job.

all in all, 2 monhts later, back to stock box + K&N panel. thd sound got too annoying.

[Dray_Templar]

Thanks SiReal, Wasn't sure what brands to look at that were decent, i take the simota and pretty good?

And anyway like you said will be able to take it off when i get sick of it :)

Did you get the SIM-CA1 or somthing else? What is the the ball park figure for the one you had?

http://www.simota.com.au/default.htm

[SiReal]

simota aren't great. but if u go to Autobarn, they're selling GENUINE K&N pod filters for $68 which is dirt cheap. Not sure if its still on or not, maybe it was a sale.

General cost of a metal piping CAI kit is around $200 to $250 and has everything u need. But replacement will be from throttle body onwards.

Or u can do a DIY CAI with CAI piping from autobarn ($25), then direct the mouth of that pipe onto your Pod. You will need to buy a connecting tube bit from stock pipe inlet to the mouth of the pod ($30ish). Then buy ur pod ($70), then a heatshield ($30). Easy to switch from pod to stock box.

Hope I havent confused u further.

[Dray_Templar]

Thanks again for you great advice and help Sireal :) Think i will have ago at the third option.. was going to have a go at it on Sunday, but only supercheap was open, and all there stuff dosn;t seem to be the qaulity i would like to use for these perticular items.

Will get et.turbo.dude to give me a hand, when i do it, and if i get stuck or need a hand will have a search here, or ask for a hand again.

[SiReal]

no worries mate. you'll need to take off ur front bumper and take teh resonator out as well if u are doing a DIY CAI. have fun!

[Dray_Templar]

just came across this CAI DIY, might help me when i do it, or some-one else at a later date :)

lol no offense man but thats funny... sounds liek you really love your car :)

[Dray_Templar]

yeah i think Honda Enthusest is either band again or dead, or just decided it's best of he does not stick around, or he has just chillied out and not posting stupid stuff anymore.

you should read some of his other threads to get an idea how much he loves his car. some are pretty funny if not sad.

anyway back on topic, umm nothing to say on topic.... Sireal thanks again for all ya help !!

[vtec_jet]

Dray i'll let ya noe wat ive got planned for my car . .

Remus Muffler inlet 2.25, custom 2.25 piping, high flow cat, custom extractors. and ofcourse a resonator or two . . i want good performance out of my accord but i still want it quiet . . its a cruiser . ;)

watch out for my car in the next 2 weeks. . big planz . .:p

On my 98 V6 Accord i removed the rear mufflers and got some tail pipes welded up with some nice chrome tips (AMG mercedes style). It actually wasnt that loud but at high revs it was quite high pitched which turned a few heads.

[Honda Enthusiast]

All sounds great...got any pics, guys?

[markc]

Here is a pic of mine. No mufflers just tail pipes and tips.

very nice champ :thumbsup:

very shinny exahust tips...keep the pics coming yeah? ! ;)

[Dray_Templar]

thats reall smoth mark, like it lots. What wheels are you running on that? from what i can see of them they look sweet and suite the car.

thanks for the pic. Reminds me really need to give mine a wash.

Thanks guys.
The wheels are 18 inch XHP Scorch. They are 4 sale too. They are real luxury style.

[SiReal]

Hey mark,

You said u had ur tips welded on? So its the stock muffler, and they just welded on new tips right? I was planning to do that with two square tips (AMG C36 style). Much appreciated if you're able to tell me how much this procedure costs.

Many thanks in advance for your help mate.

No, actually the mufflers have been removed. So the pipes were attached from the rear axel and were made to be an easy swap with the standard mufflers.
All up it cost about $160.

The quad tips will look mad.

[SiReal]

Thanks Marc. sounds great. I'll probsl keep the rear muffler but weld on two square-ish tips . btw i've got a 4cyl, so it'll be dual tips.

thanks once again.

hey vtec_jet anynews on that upgrade? if you created a thread for it could ya chuck up a link here for me?

would love to see how it turned out and any advice you have after the expiernce, and how does it sound?

[Shaggin Wagon]

mine has 2 aftermarket oval mufflers with the quad square tips on them, looks tuff.....
dray id concentrate on the conversion and then worri bout the little things like an exhaust and intake later...

as for having no airfilter, i highly recommend running one but geezus it wont blow up if u dont run one, top fuelers dont run air filters......

yeah thanks mate, I no they won't blow up in hurry with out an air filter lol, used to run mum Holden HZ kings wood with out one, lol run to shit with one lol.

Me and some Mates took our Datsun skyline with a 351 out to winton race way on the weekend, ran it in the burn out comp, and in the drags with no air filter the whole time, all we blew was the head gasket, we threw the fan belt half way throw a burn out, and heated the engine up alittle but no biggie, gives us something to do between now and next year when they hold it again.

P.S it was $250 bucks to enter your car, you can go in any events, burn outs, drag, go to woe, show and shine, Dyno shootout, drifting and free time on the winton race track to do some laps, and take mates for a ride around the track

you guys should come next year was great fun.

Mate this is so true....I just put some stickers on my automatic LS Integra and its now quicker than my other car...which runs low 11's....who would ever have guessed....lol

[mj3610]

hey guys sorry to hijack thread
what do you guys think of a catback system on manual accord VTi? muffler will look exatcly like stock (dual tip) but have that roaring sound along with the CAI. i didnt wanna touch the ecxhaust system at all but my stock muffler is heavily rusted underneath and is on its death bed, i wanted to see if i replace it with a quiet one or a sports one, they'll look the same but sound diff.
