currently i have a GSR muffler bolted to my RSR bpipe for a stock look, is it too restrictive? would an ITR muffler make a noticeable diff in performance?

 

I have another question. Is the ITR Exhaust pipe and GS-R Exhaust pipe different? If so, what's the difference?

 

I was told that the difference between the GSR and ITR is the internals*
I have a question also I am going to put a ITR exhaust on my GSR and I wonder is it worth it?

not only that, GSR has 2 inch crushbent piping while ITR has 2.25 mandrel bent, but i was just wondering if muffler would make such a difference.

 

i dont think the Muffler will make such a difference... idk

 

ITR muffler flows 30% better than stock GSR

 

If I wanted to put an ITR Bpipe in my 4door integra LS, where would I have to extend the pipe? thanks

 

where'd you get that number from?

 

It has been tested by a number of people.....30% is an average

 

Muffler is not 30% better. Its the whole exhaust system combined, header/cat/cat-back that makes it 30% better than a GSR.

 

Maybe this link will help shed some light....

get a different muffler, your gsr muffler will be restricting it...i wouldnt get a type r tho...just buy a nice quiet aftermarket axleback like the apexi ws, looks stock, quiet.

 

i have an RSR its very quiet, i just like the "stock" look tip

 

I forgot to mention I am getting the full header back sytem is that good

If the "R" muffler/exhaust is larger in diameter the whole way back, then of course it is going to have at least 30% more flow. It is simple fluids flow!!

 

THe ITR is about 2", not 2.25". And a GSR is about 1.75" I know this because i have personally measured. ITR exhause is nice for the street, but very restrictive.

 

With those mods, id say getta new muffler. Id assume you would gain a couple maybe few horses from the type-r muffler but then again u know what assuming can make ya.

please fix the search/archive function!!! This is the second time this has come up in under a month...

 

I just put an ITR muffler on my LS. It bolted right up, but I've heard the exhaust parts are a little different on 4 doors and GS-R's, so I don't know about them. I wont have my ITR b-pipe until I pick it up at UPS tomorrow morning, but the muffler alone seems to make a slight improvement. I expect that I won't see the full benefit until I get my ITR b-pipe and DC 4-2-1.

Comparing the LS and Type-R mufflers, they are almost exactly the same size/shape, but the Type-R has a nice looking tip, stainless steel mandrel bent piping, and the internal enhancements (I've seen several articles about those). Here's some side-by-side pics:

Wow coo pics Weston...that ITR muffler looks mighty swell!

BTW is there a difference between LS exhaust and GSR? So would it be worth it to swap my 95 LS muffler in favor of my friend's 95 GSR muffler? He said he'll give it to me for free if I want it

 

From those wheels in the pix I know you have a 98 LS huh heheh

 

Actually, it's a '97 LS with '98 LS wheels.
