now that im getting a little older, im starting to like the sound or lack there of, of the stock exhaust

since iv decided to finnally pay off my car and keep it, i was doin some thinking, iv got 75 on the car, and iv driven it pretty hard, iv had it since 20k, so i was gonna do a mild rebuild, new rings, new bearings, etc, maybe ctr pistons, maybe jdm b16 cams, not sure yet, if i got them id get a nice set of cams

so i was wondering, if i were to get a jdm itr header, have it ported a little, a nice aftermarket cat, and use my oem type r exhaust, whould i loose power keeping the stock exhaust, if i got some pistons and some nice cams, nothing crazy, maybe skunk2 stage 3's

or iv also got a spoon n1, i was thinking keeping the oem b pipe and using the spoon n1 like i am now

a couple questions:
1) b16 cams? wtf for?
2) you're worried about exhaust noise, but are running a spoon N1?

 

Typical bolt-ons and the power won't loss won't be that noticeable, but you start doing pistons, cams, etc and your top-end power is going to suffer--a lot.

I was thinking about the same thing but I dont have cams just adj cam gears....but would oem itr exhaust be good for daily driving and the spoon N1 for racing or on the strip????

 

my stock exhaust supported 209whp at the wheels.

 

dorry didnt mean b16 cams, meant b16 pistons


clip the apex, thats what i like to hear, thanks alot

 

throw that N1 in the dumpster, buy a Fuji RM01A and you'll never complain again. Sounds close to stock, nice but not overbeaing at WOT, and will only increase your performance.

 

what size if the piping on the fuji?

 

65MM OD if iam not mistaken.

 

Or just get a simple custom setup. Like mentioned N1 style mufflers are usually loud. 2.5inch mandrel bent piping with an ES Oval or magnaflow oval muffler. The key is having a big enough resonator. 22inch magnaflow resonator should give you a low/deep sound and not be super loud..

 

rm01a is 60.5mm od, same as most jdm exhausts

 

if i were to get a nice header, with a say carsound cat, and custom 2.5" midpipe, with a 22'' resonater, and used my spoon n1, do you guys think it whould be really loud?

even with the cat and the resonater?

really loud? probably not.

louder than the "sound or lack there of, of the stock exhaust", yes.

 

i have an ITR with k20a2 (JDM 98, not sure if exhaust is the same diameter as USDM?)

Mods
IPS K2 cams(crower springs, Ti retainers)
RBC
DTR/SSR 4-2-1
K-pro
Exedy flywheel
Custom short intake (will be going for a cai when funds allow...only need a bit of pipe lol but times are hard)

but.....i am running the stock DC2 b-pipe/axle back cut short to mate up to the dtr header. car feels fast, street tuned, never been on a dyno yet.

(i'm a bit short on cash currently, so dyno and exhaust will be at least a month or 2)

I always planned on going 3 inch eventually, but running with the stock exhaust i just love how quiet it is, and also how the car looks totally stock (apart from an eibach pro kit slight drop in ride hight).....even though it's an R, its silver, with oem grey wheels, black recaro's and just seems to blend in here in the UK. (i was even sat in my car parked next to a friend in his CW 98 spec red recaro's when some lad came over, started getting really excited about seeing a 98 spec JDM, asking him loads of questions about it......he was there about 10 mins having a really good look around my friends car, and didnt even notice mine at all. we were parked right next to each other side by side in a row of cars lol........so yeah, i like the fact to 99% of people its a sleepeR.

anyway, back to the point, my car feels as fast as i expected it to, but ive never run a 1/4 or been on a dyno. but do i have like 10-15hp crying to get out, or am i just loosing a few that i'd hardly notice on the butt dyno? will i 'feel' a difference in how fast my car is getting a more free flowing exhaust system?

any estimates on how much hp i'm losing out on?

 

bro theres NO reason to change exhausts for street and track driving .
thats like taking something thats fine for both and replacing it with such a similar part , the only diffeence youll " feel " is the sound will make u think its faster ,. but it wont be

 

Yes, but what would that have been w/ a higher flowing exhaust?

 

there is nothing wrong with a stock exhaust. Honda didn't spend thousands of hours tuning this car only to put a **** exhaust on it.if I'm not mistaken, the jdm exhaust is 2.5", plus a tubular header, plus higher compression pistons, and it only makes an extra 5hp. You really think an aftermarket exhaust will make that much of a difference?

 

hmmmmm arguments with a 4 year old thread. good stuff. good points in here though

 

Again you are talking about a stock car, while the poster is talking about a modified car. This changes the game quite a bit. Also, Honda designs it exhaust to be a compramise between power, noise, and a myriad of other factors. To say that Honda put a perfect exhaust on there from the get go is a bit of a misrepresentation if you are speaking about power production.

 

Absolutely! Nothing about this particular debate has changed in 4 years... actually more than 4 years.

 

Didn't notice how old this was, lol.

 

that's true. I'm not saying they put a perfect exhaust on the car. Only that they didn't design the system with only fuel economy and noise in mind. You can get more power with an aftermarket exhaust, but I think it's pretty minimal by itself
