Hey I was just wondering if the ITR exhaust is performance enough so its not holding the motor back.... I know its more flow efficent than the GSR... But I dont want to have a COP ridding my *** for exhaust noises, or is there and exhaust thats Nice quiet but packs a good punch thanks

 

Anybody Bump

 

the itr exhaust in stock form does have a couple bottlenecks. you can either fix them, or get an aftermarket set up.

 

if you fix the bottlenecks, will it out perform aftermarket exhaust?

 

Which particular aftermarket exhaust(s) are you comparing it to? The stock ITR exhaust has bottlenecks, inconsistet diameter tubing, and a chambered muffler. Most aftermarket exhausts will only have a bottleneck at the cat mounting flange and use a straight-through muffler.

 

SO like a GReedy Evo will be a good choice or the RS-R... i want to keep the sleeper look, i dont want the bling of the EVO enen though it sounds good

 

As for the bottle necks...


Costly but will keep the police away and let you pass inpections

 

Im not really sure on the ITR exhaust, but what does all that bottle neck stuff about ?? i mean like whats bad about them, and so all that pic is about is welding on a staright piece of exhaust so its not pufed out ?

 

What's bad? Impedes flow.

If you can cut and then weld a piece on yours and make it work then go for it. But let me tell you. the stock ITR exhaust is SS and the part I got from SMSP is also SS, I'd like to see you TIG weld it. And welding SS is a ****.

 

Your best bet is to get something custom made for you. Or buy an aftermarket system like T1R or Mugen. Most aftermarket exhausts are loud with a few exceptions, Apexi WS & Mugen. If you get a custom job then choose your muffler wisely. SMSP has made some the most amazing set-ups I've ever seen. Mild to wild. Bling to sleeper. You get what you pay for. Fixing up the stock exhaust just doesn't seem worth it.

 

Evo is not lo-profile.... read my sig

-aoib0t, who can't believe it came in handy (the sig)

 

ITR exhaust outflows the GSR exhaust by 30% FYI

 

i believe omniman made like just under 230whp on a b20z w/ gsr crank/rods, hytech header, but 2.25 exhaust.

my other friend made like 216whp open header and i think 209 w/stock itr exhaust bolted on.

unless you've got a hardcore build, the most i would do is test pipe or highflow cat/custom b pipe, stock itr axleback.

 

SO your telling me i should get a ITR exhaust ? cause thats what your SIg. says... Ive hear Greddy EVO's and the more RPM the less loud they are, They are also 50 state legal.... Well Is there any other Exhaust and header combo i should get ??

 

I think 50 state legal IF you use greddy exhaust AND greddy header. I had asked my Greddy dealer for the original 50 state certificate but he said since I used a non Greddy header, it won't apply

-aoib0t, who paid the city for the "crime"

 

SO i would have to get the header and exhaust combo...."You know if you have a Type R exhaust, you will make just as much power and it will be quieter... just something to think about" this is what this topics about... but I guess the best setup is the Greddy kit

 

Even so, what's 2-3 HP for, I assume, a street-driven car?

I'd take a few HP hit for a nice quiet exhaust and one that keeps me away from the cops.

Those guys running around with N1 exhausts on their otherwise stock car freaking crack me up. All they do is make noise and very little power over something that could be a lot quieter.

 

I love the way the stock ITR muffler looks; is there any way to hook up larger diameter piping to the stock ITR muffler??? That would be sweet!!!

Yaits a street car.......... so what performance header shall i get ?, I will just hook up a 2.5" exhaust all the way to a ITR muffler... and blow a semi-performance with little noise

 

Hytech

 

so lets say you kept the stock ITR muffler and added a 2.5 mandrel bent catback, how would that perform?

 

MY setup

DC 4-1 &gt; resonated testpipe &gt; Stock ITR catback removed bottle necks

All the testpipe haters need not reply.

 

I've got the DC JDM header, car sound cat with Apexi WS cat back and you can't hear a thing. Honestly, it sounds stock as can be, I love it. As for keeping the stock muffler look. If this Apexi WS was too loud (isn't really loud because it is a muffler) I was going to get like a magnaflow or some other free flowing muffler and maybe put that polished ITR muffler tip on the end to keep it looking stock but still be performing a little better.

I like this.

That R Catback is 2.25 correct.
