Exhaust on a 5th Gen

[Mike_]

Hey guys, got a bit of a dilemma.

So far with my car I've done almost everything i want to (aside from detailing) except for one thing:

The Exhaust.

There are a few reasons that, to date, I haven't yet got a catback system. Firstly it was insurance, but the big reason is that I honestly and just not sure what to get.

I have had numerous suggestions and ideas and I have had numerous quotes.
One thing I have been told though, is that with VTEC engines (such as mine, F22B1) when it hits vtec you get a noticable, loud, "bark" or "growl" for the duration of vtec.
For this reason I have wanted to steer clear of the cannon style exhaust, as apparently with these (and with my air intake, which is particularly loud), the growl can get VERY loud, and sometimes sound bad. Therefore I have been looking at a Twin Upsweep muffler (I trust you all know the ones), as I am told (and I have heard) that with a four cylinder car they eliminate the fourbanger "buzz".

But I'm not sure I like the look.

I'll be going with a 2.5" system no matter what muffler

Here is my dilemma;
I like the look of a cannon, but not the sound
and I like the sound of an upsweep, but not the look.

I want it to look AND sound very nice.

Another option I am investigating is TWIN twin upsweep mufflers
This will look better than just the one. I understand that this will not increase power to the same extent, but my car is really just for cruising. It's never going to go particularly fast.
This, however, brings a large cost into the equation, and would be 2.5" split to two 2.25" pipes

My question really is, for those of you with 5th gen's, or even vtec engines in general, What sort of tone do you get from your exhaust, and what type is it? What sort of costs are involved for what you have and were you happy with the result?

Does anyone have any other suggestions as to what might look and sound good?

Thanks guys, sorry about the essay!

2.5 is a bit big for an f22b, go 2.25 mild steel press bent with a resonator and muffler.

get a sports muffler for the back, ive just got a red back muffler with a twin 2.5" chrome tip on it. its very inconspicuous ( cops dont look twice at it) and it sounds sweeeeeeet.

it has no buzz, it has a nice hum to it.

[Mike_]

so I've been told re size.

I would go for a 2.5" because there is a possibility that I will add cams and a vafc later on, so it leaves the door open for further mods.

No matter what i get it would also be mandrel bent.

I'm more concerned for the muffler. Have you got any pictures of your redback muffler? how much did it cost? is it dry and throaty or does it sound smooth?

Can you tell us what horse power you plan on getting out of your f22b that would require a 2.5" diameter piping?

it's up to you in the end but a 2.25" will be better for everyday driving, its not like you have a motor that even produces power after 5500rpm, so it doesnt need a big exhaust to cope with the flow at high rpms cos it doesnt rev high anyway. basically with a 2.5 all you will acheive is less low down urge and more noise.


Not much point adding cams and a vafc as the power gains per dollar spent will not be worth it.

if you are going to throw money at it, go turbo or if u want N/A drop in h22a

[h22a accord]

i'll get you a pic when its daylight :)

There is no truer statement when it comes to the F22b's.:thumbsup:

OK a little help.
This is my first post since i got my 04 accord Euro 2.4L vtec.
Im in the same place as mike_.
I want a new exhaust possably just cannons but dont want a buzzzzz.
The exhaust place said that cannons wont fit on it coz of the angle of the existing exhaust box.
Has anyone with a euro changed the exhaust
If so how did you go about it

[dundas]

mike, ill show you my exhaust on sunday mate

Euro boy, do a search.. heaps has been written up on the euro accord and exhaust ^_^
get an oval muffler ;)

[Mike_]

Hmmmmmmmmm. I'll look into 2.25 a little more then

I'm honestly not sure why though, but im quite committed to the f22 engine hehe...
I'd rather see what I can do with that than swap in a h22a.

Maybe boost it later on.

MUFFLERS MUFFLERS MUFFLERS MUFFLERS!

Oh and im looking forward to sunday hehehe im gonna kick your asses! lol jokes

I might have the soultion to your problems. skunk 2 in the USA produce a bolt on 2.5" catback exhaust with a cannon muffler, and it comes with a removable silencer. It is dyno proven and features top notch welds, bends etc with the only downfall being price, around $1300-$1500 AUD landed after tax :(


Check out www.skunk2.com (http://www.skunk2.com) for more info! hopefully I will recieve mine shortly and have it bolted up before I install my turbo setup :)

What is your HP goal and budget?

Raz

[dundas]

sorry didnt realli get to show u my exhaust man, should of taken you on a lil drive around the block or something. I tried giving it a few lil revs while i was leaving.

[Mike_]

hp goal is not particularly high, i just dont wanna swap engines. Budget not an issue as it'll be done over a long time...

And yeah dundas i heard that, sounded quite nice! - im pretty sure i saw you in the city once :P

Thats ok, i got a good idea of what to expect :D

And thanks for the info on skunk2, I'll check it out!

[razaman]

Do you have a goal or goal range or are you just going to spend your cash and see how you go?

[dundas]

sounds like Mike has lots of $$ :D wanna share with me ???
yeah, just sum advice,,, dun get anything too loud it will piss you off on long drives...that is why the 2.5 will suck too LOL- But if u plan to turbo ur car, try get a bolt on so if u require to change the size of ur exhaust system, you can then get a new one and sell ur bolt on.

[94_Accord]

hey mate,
if ur unhappy with the cannon, why dont u have a look at my kind of style with the twin tip muffler. its a nice sound, but not too much to handle and does not giv u cop hassles. it may be worth a try

[h22a accord]

pictures as requested. its discreet, you cant see the muffler box unless you look under the car and it gives a nice note.

discreet is the safest route of all.

[Mike_]

nice guys. im after something that.. how do i put it... looks like it comes stock on a high performance european car... i like the idea of twin tips, and as i said dundas, it will be over a long time ;)

[dundas]

hey H22a.. sorry forgotten ur name.. whats with the tyre marks ey??? sum1 get a lil excited...

check out magnaflow.

Got a couple HP numbers off some US accord forums.

One member has I/H/E and a few other bolt ons = about 138hp/150tq to the wheels

Another member: ive seen 149 hp to the wheels on a 2.2cl with i/h/e/p cat, cam gear and ignition.

american dyno's give a much higher reading than aussie dyno's so you cant compare the 2. its just pointless. american dyno's are inertia dyno's and aussie dynoes are braked.


I have a friend in america and his h22a accord with only i/h/e reads 176whp on the dyno. the same car in australia would read around 150hp, this was taken from www.dynamometer-info.co.uk (http://www.dynamometer-info.co.uk/)

An inertia dyno, uses a heavy solid steel drum, and no brake! The drum is free to accelerate. A computer logs the rate of acceleration, and as it knows the mass of the drum, it can plot the power required against either road speed, or real time engine RPM.



A Brake type dynamometer measures power by "braking" the drum or roller (or the engine in an engine dynamometer directly).
it then uses a load cell or spring balance to measure the torque required to hold the engines RPM steady. Now, Torque x RPM = Power so we have the power!

I wouldn't say it pointless, and I wasn't trying to compare dyno's.

Even if there dynos do read higher (which the do) it still shows the gain from stock.

Raz

[h22a accord]

Point taken razaman, I think you missed my point, i was demonstrating to others that may not have known about the different readings between AU and US dyno's to avoid confusion when/if an ozhonda member went and spent hard earned on an f22b with i/h/e, cam gears, cat, ignition etc expecting gains up 150whp and then discovering that they are only producing 125whp because they testing on an australian dyno and finding out later that the whp figure you had posted were from an american dyno.

For the money they had spent on good quality mods including installation and tuning on their f22b with the above mentioned mods they wouldnt have been too far off the price of installing a h22a which will instantly if you 150whp on an australian dyno, not to mention the benifets of a low km engine with the possiblility of a factory LSD in the gearbox.

[razaman]

Yeah sweet as mate!:D

I know about the dyno differences but others will not.:thumbsup:

I posted the numbers originally because Mike was talking about building up the F22, I personally think it's an exercise in 'money wasting'. He didn't have a goal for HP or a budget. Once he sees the cost of getting 20-30 HP out of it I think he might change his mind.
