Ok everyone, I need some advice. I currently have extreme duel exhaust from Gibson on my truck and have been very happy with it. It has held up very well. My question is if you wanted to stay with a cat back (which i do)
is corsa or magnaflow any better then gibson performance wise?

 

performance wise, no.

 

Agree, but sound wise yes.
I've had Gibson and now Borla but the sound from a Magnaflow is impressive, Corsa even moreso.

 

I loved the way my corsa sounded with my LS2 X1 combo
