i just took off my turndowns and put on the factory tailpipes. i found out that the mufflers are 2 1/4 in will this hurt my performance? i have an 2 1/2 h pipe on, it just the tailpipes.
i had a 2 1/2 in h-pipe and 2 1/4 flowmasters and tail pipes on my car and switched to 2 1/2 race bullets and dumps and it made a world of difference....it definetly felt like my car was revving better and running smoother
Its the rear most part of the exhaust, it is flowtubes from the h, mufflers, and tailpipes. All refered to as a catback, but if you have no cats, then is it still a catback
A cat back is a bolt on kit that you can buy. Basically you leave from the motor to the catalytic converters alone then add mufflers and tailpipes as a kit. This way you get a little more performance and a better sound but are still emissions lega.
