2015 Mustang GT exhaust
 

Traded my 2015 V6 for a used 2016 Gt premium with performance package, anyone selling a good performance exhaust or know whats the best to put on it, I like the corsa extreme catback

Congrats, if you like the Corsa Extreme Catback, go with it, "best" is pretty subjective for anyone to tell you how your car should sound.

Thanks you know of any deals or where is a good place to buy in canada

Congrats, can't go wrong with Corsa, it's expensive though. Roush has a nice sound too for a lot less money.

[Thanks I don't see a catback roush exhaust for 2015 and up GT

Roush is an axle back system
