dual exhaust is very helpfull for peformance and miliage however if you use a pipe too big you lose low end torque and on newer trucks you can use a single 3 inch exhaust that works fine for 300 hp and less. and the phony dual exhuast that is nothing more then a dual outlet muffler is chivvy engineering and nothing looks dumber then a phony dual exhuast. well maybe a lowered halfeton or a 4x4 with no front driveshaft. my drivel for the night steve
