It's crossed my mind, but I can't imagine any kickass stereo that can be gotten for the price of entry to a decent exhaust.

Someone say weight?
JUST S/C it!!
Heck I am dynammated with a larger wheel and tire package. The S/C gives me what feels like factory power again!!

I know, old thread...but this bears repeating.
BACKPRESSURE is an automotive myth. You do NOT want backpressure in ANY exhaust system. Period. That myth was started by individuals who do not understand fluid dynamics. The purpose of a PROPERLY sized exhaust is not to create backpressure, but rather to maximize scavenging efficiency. When the piping is TOO large, there will be minimal restriction on flow, but the exhaust charge from each cylinder will also tend to "dwell" in the piping, rather than scavenge properly. When this happens, the net effect is WORSE than a smaller, stock-sized exhaust. In a "stock" exhaust (or rather, one that's properly sized for the engine displacement and power output), each cylinder's exhaust charge creates a vacuum in the piping as it scavenges. This vacuum then "pulls" the next sequential exhaust charge out of the pipe in a more efficient manner. (About the only thing MORE efficient would be zero exhaust piping).
Vehicles with a "too-large" exhaust will usually feel a bit more sluggish on the lower end, but do better up top--where the piping is more "in-line" with the needs of the operating RPM's/output.
