Ok, I had Strup headers and test pipes(non-resonated) installed yesterday and I have the OEM cat-back. Now, I thought it might rasp, but it's pretty bad sounding. Do you think adding a cat-back would help eliminate the rasp or amplify it? Should I just put the stock cats back on? I cant handle a little rasp, but it makes me cringe everytime I hear it!

I was looking into the Greddy Evo, but I dont want to spend $1000 and still have rasp.

 

resonated test pipes wouldve helped, but as for putting the cats back on, thta should help as well. But if it was me i wouldve just gotten resonated test pipes if you really hate the rasp.

 

But I really want to keep the test pipes if there is a way to eliminate rasp through other parts of the exhaust. If not, then stock cats go back on.

 

have an exhaust shop put resonators into the test pipes

 

Rasp is overrated.

 

Well, Im putting the stock cats back on tomorrow. I'll just save for a cat-back to go w/ my new headers
