I got a couple questions about the ITR and GSR muffler is there any difference or are they the same. I want to get something that looks kinda sleeper for my EK coupe. I already got an a custom exhaust that I have had on there for about 4 years now but it is loud. I wanna get something quite that will not hurt the performance of my car to bad and give it a little bit more of the sleeper look even thought I got some Rota's and a cf hood. I dont want the whole exhaust just the back half. Or is there some kind of aftermarket muffler that I can get that is quite?

 

Here's a visual comparison.

in addition, the ITR muffler is internally different than the GSR
ITR is freer flowing due to different chambering
