I have been taking this into consideration. How would a resonator delete sound with the 5sfe? Same with test pipes (cat delete)? Anyone have any info in regards to sound or performance?

Just resonator delete with stock muffler? Probably not very good. I wouldn't delete the resonator. Here's what mind sounds like with a cat delete (with Manzo header), Vibrant Resonator, and Tanabe muffler.

If you just delete the 2nd cat then it wont be any difference. I've tried a decat on my 2.25" catback and it barely got a little bit louder. Barely noticeable. If you want sound just get a header and straight pipe. Lol.


Btw, you can YouTube "silly97 magnaflow" and you'll find my vids.
