Hey everyone I registered here today to see if I should buy a Magnaflow muffler or exhaust for my 03 g35 coupe 6mt.

I have two main questions:
1. Would they sound the same?
2. How much difference is there in regards to performance gain to muffler vs. exhaust?

 

1. It would not sound the same.
2. you might have a loss in performance, the g's don't really gain from minor mods like intakes and mufflers.
