Ep3 - Intake and Exhaust

Hey there,

I am just wondering which Intake and Exhaust you guys are running and why.

My car is completely stock and planning to do some upgrade for better air flow and sound, I'm not chasing for more power in this upgrade.

I did some research and most people recommend the Gruppe M intake but I think its abit too much where the intake needs to be coming out from the bonnet. Anything else I can look at?

For exhaust. I think the HKS Hi Power sounds good http://www.youtube.com/watch?feature...&v=NQuelyu8ql0 .

Thanks alot!
Tony

PS. I am totally new at mods so any advice is much appreciated

get an Injen if you don't want to spend the amount for the Gruppe M. sound is good.

Many EP3 owners have the Fujitsubo RM01A and they say its very good, I don't have one myself but my mate has one and doesn't regret getting it.

Ive got an aem cai with J's Racing 60rr catback. Sounds great.. looks great. And ive had a noticeable difference in response.

Custom exhaust brah
Provided you got a good welder

I've got the RM01A. Virtually silent until you hit vtec. Highly recommend it.

I don't think there is much point getting headers on the Ep3 if you are looking for the full I/H/E. It's comes stock with a 4-2-1 so not much to be gained. Food for thought anyway.

ive got fujita cai and mugen twin loop. so far its the best sound ive had on all my honda cars :D the noise u make when u hit vtec = gg and very quiet on idle

Not true man at all, sorry.
J's racing header will give you up to 139kw's and others up to 147kw's. Well worth it IMHO.

Haha. Thought that would get a response. I read somewhere that there's not much gain to be made. There is always going to be something to gain from any aftermarket part but would be the least bang for your buck out of the intake, exhaust and header. That much is for sure.

Thanks for all the input, still doing more research before I get the parts.

I found this on youtube, hope to share it with everyone

It is a DC5, but I guess they will sound the same?

At the end of the day, unless you get a tune, any power gains you get from I/H/E will pretty much be negligible.

I'm running Toda exhaust and Gruppem btw.

word!!

i had Fujita CAI and Kakimoto mid pipe + Spoon Street muffler. if i get to do it again, i'd get Injen CAI + Mugen twin loop.

I`ve got a Feel`s cat back, sounds great but is a bit on the loud side. I too would choose a mugen twin loop, its much quieter down low. I progressively upgraded my intake, from a drop in filter for the airbox, to a 3a racing filter in the stock airbox with a cai pipe, then changed to a custom SRI with the 3a pod and 2 cai pipes. I finally opted to buy a gruppe m. Which by far had the biggest gain and noise from all the intakes i`ve tried.

If your just after sound, any aftermarket muffler will do. I found the SRI good for noise and moderate gains in power, but it does get quite hot sitting directly open to the headers.

Considering it is the Type R, the japs have made power gains from bolt ons very difficult. Yes you can get marginally better headers intake etc etc but I wont be wasting money on any more except for a new clutch/flywheel. Internally is where you get decent gains from the k20a. imo anyways:) but that said.. soooo many more dollars:(

thanks for all the useful info.

I think im going towards Injen CAI + HKS hi-power. unless someone can point out its not a good setup.

you won't regret with the Injen in terms of value. just stay away from water and you will be fine.

how much are you paying for the HKS? is it cat back or axle back?

I love the Spoon Street muffler though. I love the sound I haven't see another soul in Sydney that owns this :)

I have just got a mugen center pipe which I'll be replacing the kaki with. Soon I've have a mugen/spoon hybrid.

The resonator on the kaki had broken on me. Replaced it with a custom one but felt too loud for my liking. Although sounds nice when giving a good spirited run.

hi Pete, nothing wrong with the Spoon Street and that's why i bought it. just that i like the sound of my fd's mugen twin loop slightly more.

so how did the resonator break on the kaki?

The things inside slowly collapsed. Drove me nuts! So I had it cut and re welded with a cheapish custom resonator.

I havent got the parts yet. Just taking a look where to order now

EBay. Cheapest

i too am looking for headers and exhaust for my ep3. i think ill be goign for the RM01A for exhaust.. but im still deciding on what kinda headers to go for..

maybe buddyclub?
anybody care to help and throw me a few more headers i should maybe go for..


i got the gruppe M cai... sounds awesome.. but hella expensive tho :/

Kiddracing headers are pretty good for the price.

Toda ftw

if anyone selling stock ep3 muffler pm me!

Got mine as part of a group buy (with hi-flow cat welded on) for around ~$1900.

^dammmm!

haha you get what you pay for though:P

I'm running a TODA exhaust (droopy tip) and a HKS Hi-Power intake.

TODA exhaust is really great if you daily drive the car. Quiet enough on idle, very livable, sound great when you rev up and absolutely sings on VTEC :)
Once the cars warmed up and during a spirited drive you also get the odd "pop pop" backoff sound too which is always nice. The TODA is also really raspy on revs, sounds very clear and measured in its volume, I don't think I can really fault it, such a high quality bit of kit! In regards to intake, unless you go for a gruppem most CAI/SRI are a much of a muchness and with a high performance car like the EP3R you're not going to get much power from any breathing mods unless you add an ECU and get it tuned, even then its hard to get huge gains for minimal money....unless you plan to go internal work and thats a whole new ball game!

I picked my HKS intake up for less than $100. Basically just an SRI pipe and a pod filter. Sounds crazy loud on VTEC, performance gains I'm sure are NIL, but sound-wise sounds great. Will most likely change to a gruppem in the future.

Considering how much you can get one of those PLM/Kiddracing headers, it is very expensive. I don't regret the purchase though, as I know it will hold its value when/if I part out. I also wouldn't recommend dealing with TODA AU either. Waited 6 months for my headers and ended having another member driving up to Honda Nats to pick it up for me.

i know i wont regret the purchase either.. id only regret if i dont buy it..
but i wont be getting it anytime soon... hopefully within 6 months time...

just need for them to respond back with a price.. or maybe find a third party who will help me out with price and purchase and etc etc

Kenny I can ask my mate to see if he can get it cheaper for ya. He quoted me like $1150 delivered for a fujitsubo exhaust from Japan

Sorry $1198. =]

kenny if your still keen on the group buy ill be down! ill probably get it further down the track, still deciding over a n1spoon haha

im very keen alanalan.. but not anytime soon tho..
is there like a group buy on atm?

When you getting a pod filter, eg Injen one. Is it better to get the short ram version?

If you're scared of hydrolock - yes; if you want gains - no.

youll be fine in the wet weather. Just dont drive through deep puddles-_-

I'm guessing short ram is also a lot easier to install ?

Yep, easier to install the short ram because for the cai you have to remove front bumper and cut hole behind the bumper guard.

Not worth the short ram though unless your just purely after sound.

True thanks, how about the gruppe M? will that be easier to install? I never done any mods myself before so i wanna try something easy first

Its pretty straight forward to do the GruppeM

will i need a tune after i install the intake? im pretty keen on ordering one :)

Gruppe M is relatively easy to install except you have to remove the wiper guard on your windscreen and replace with the one Gruppe M supplies.

Also take note that if you have a front strut bar, not all front strut bars provide enough clearance for the Gruppe M. I have the M&M honda front strut and it clears Gruppe M fine.

Unless you've done other modifications no point, if anything the stock ECU might compensate for it somehow =)

like to add the J's Racing 2 point Front struct clears it as well, the Cusco one wont, only reason why i changed to a j's racing from a cusco

disregarding 2nd hand
where did you guys get your toda cat-backs from?

Just another note. Cleaning the gruppe m = you have to take off your strut brace too.

You can ask toda Australia.

I can recommend someone who can help you out too

alot of members say Adrian isnt the most responsive of fellas

And then some but I didn't wanna mention anything.

I just bought a fujitsubo rm01 a week ago. Getting it installed tomorrow. It was like $1278 delivered

How much for installation?

Did it at shift performance for $80

If you have a jack and jack stands you can change the exhaust easy.

yep thats right. cept i dont have stands. :)

80 bux is a pretty solid deal considering axle stands go for about 60 lol. Well atleast the ones i bought.

is it hard to install CAI?

Will this be a good intake? AEM V2

trying to install myself but i have no clue really :/ dont wanna break anything

I'd go for the Injen cai if I were you. A lot of good reviews out there about it.

You have to remove the front bumper, cut a hole in the fenderwell (the wheel guard) and remove the battery and bracket during installation. Quite a tedious task if you ask me, but worth it :)

+1 for aem. I don't have the v2 but I have the cai. Not to bad to install and very decent price. If injen is the same price.. and reviews are ok go for that one. But a cai us a cai. Little to Ho gains apart from response and noise. I can't justify spending more money for just the name when results are the same.

This was the first ever mechanical type of thing that I DIY not to hard.
