Quote: with x pipe 3 and 4" exhaust they have today,other then sounding like a top fuel car there is no advantage i believe..plus u have to re jet ur carb for open headers..look @ the turbo and pro charge cars w exhaust..
most of those "exhuast" systems are nothing more than a way for people to say "yeah it has exhaust" They consist of big pipes and mufflers that do anything but muffle the sound and end in dumps in front of the rear wheels. Some of those things are as loud as open exhaust. A 3" complete system, including tail pipes and mufflers (that muffle) will restrict exhaust flow.
