im looking to but a new exhaust system on my max. I was wondering whats the difference in getting a brandname exhaust sytem such as greddy or comptech ect. or getting a universal cat back exhaust system job by this guy down the street for 200. Whats the difference, i know there both just pipes.

 

you wont see too much of a difference between the custom muffler shop catbacks and the name brand catbacks.........your mostly paying for the name

 

as long as he mandrel bends it then its fine
