your not going to feel any peformance gains by just bolting on an exhaust if its in good condition I would go for it though.

 

Hey if u can still get that ITR exhuast for 120 but don't want it, let me know! ahah!

 

I have an ITR muffler. I love it. It looks great, black can and nice tip. It buzzes at times, but other than that I think it sounds great.

 

I picked it up awhile back ago and I am liking it. The sound is a little better than stock and it looks much better.

 

the stock itr exhaust deff sounds a little better than an ls....Because i had an LS and now i have a gsr with the type r exhaust and its deff a diff noise...I also had the WS on my ls and im going to get rid of the type r exhaust for the WS cause its just nicer and sounds alittle different
