hey guys, i just recently bought the Is-f and i need help deciding on which Cat Back Exhaust system to go with...
i keep looking up diff types on youtube but im still so indecisive...
i looked up:
Royal Exhaust
Borla Axle-Back Exhaust
Joe-Z
SURUGASPEED
if anyone out there owns these exhaust systems and can give me some feed back to which one i should go with that would be greatly appreciated!!
as well as i was wondering if they all add the same more or less hp to the car or are some of the systems give out more hp then others?
