This is a "must do" mod if your not doing an exhaust system right away. I paid $50.00 to have the local exhaust shop remove it and put in a straight pipe. The rasp is only there when you first start up the car and then it goes away. The sound isn't all the annoying, well to me it wasn't. You'll be used to it in no time and then thinking about getting true duals. Also FYI, removing the resonater DOES NOT improve the performance, thats all in your head because of the added sound, sorry
