Is there any truth in what i heard that you must have a cat back in order for n2 to work properly?
Bob97 RS/ Iceman intake/ n1 style catback 2.5in exhaust/eibach sportslines / momo shit knob/ 18" Velox scythe wheels wrapped in Toyo proxie 225/40/18 tires)/ Indiglo guages/ custom fiberglass
You don't have to have one, but it would be helpfull if you do.
