Here's the exhaust setup currently:

2.5'' High Flow Cat
2.5'' Crushbent Piping
2.5'' Thermal Straight Thru Muffler

The car gets pretty loud. Higher RPM...gets pretty damn raspy and low rpm it's a lower tone..but still quite loud.

So I'm thinking...what if I put a stock..say...gsr or si muffler? That should quiet it considerably right? I know top end will suffer..but when I go to tracks...I'll probably run open header...or do some exhaust cutout part.

Main reason I wanna do this is cops in CA are pretty ****. The car itself looks stock...but the sound would give it off. And if they pull me over for the exhaust..i know the hood will be popped open also. Then the engine swap with no BAR certification, no CARB EO#s, blah blah blah...it'll just be a hassle.

So you guys think the muffler would do the trick? Or maybe just a resonator?

no for the thermal anymore

 

doesn't thermal offer a "silent" or whatever modification to any exisisting exhaust if u send it back to them? you may want to ask the Forced induction crew since many of them run thermal exhaust.. but I would switch to either a ITR or CTR exhaust both are basically 2 1/4... or order an older RSR series from Turboimports..but your car is TURBO correct since u are running a 2.5 all the way.. if not just switch it over to a GSR if u can't find anything else...I currently run 2 1/4 cat.. 2 1/4 piping mandrel to a stock dx exhaust I so hate it so I'm getting a ctr stock muffler to bolt up

 

no..not turbo...all motor setup

b18c1
injen race cai
jg header ib modified 2.5'' collector
and the rest of the exhaust setup i posted earlier.

 

then why the 2.5 If you went with a 2 1/4" you would drop sound and gain more needed back pressure 2.5 is kinda big for all motor

 

just get a es or dynomax and paint it flat black

 

I feel you! Thermal

I have an Apexi worldsport . It's very quiet and will give you a little better performance than a si or gsr exhaust.

 

i wanted to put a stock si muffler on my car w/ the 2.25 piping but the guy at the muffler shop said it cant be done ?

whatever, i sold the muffler anyway.

 

um no its not.......i even heard some all motor guys going with 3"

 

maybe sticking a resonator somewhere in there would help cut back on your sound problems.

 

or a glass pack

 

3" on all-motor?! Here, read this: http://modernmusclecars.net/articles...tdynamics.html

 

obviously he lied to you...

i'm running a jdm ITR header, carsound high flow-cat, 18" resonator, 2.25 custom piping and a 00 civic si muffler. its quiet, looks stock, sounds sorta like stock, my intake is louder that it. i'd rather loose a little bit top end than get a ticket for modified exhaust. IMO

wassup Rod, its joseph, get an ITR muffler and a resonator

92cx b16a

 

get a real long magnaflow resonator

 

or you could just leave it the way it comes... the es still has that "stock" look

 

A resonator will quiet it down.

 

Hey wussup Joseph. Dude...I would get an ITR muffler but they're hard to find and overpriced.

I don't wanna get an ES Oval simply because it'll still be loud. Straight thru muffler...same as the one i have now. Yea I know...the ES looks stock..but mine doesn't look flashy either. I had a 2.5'' tip welded on...so it looks like a puny muffler.

I guess I can try getting a long resonator...hopefully it'll work...I'll just be pissed if it doesn't. Will have to pay twice. Here's the exhaust cutout i wanna get:

Whatcha guys think?

-Rod

 

resonators and glasspacks help to quiet things down.

 

I have a 92 Si exhaust for sale if your interested. E-mail me socrkid5@mindspring.com

-Jake

 

dude just go for a gsr or 00 civic si muffler, and get one of those, i'm for sure getting one.

 

screw that!!

THERMAL KICKS ***!!!!!

i was talking about him not having any for thermal...

what didnt you like about it?

 

C'mon... I'm running a 2 1/2 from header thru a resonator and then through a supertrapp...... LOUD and RASPY.... but its not a street car
