I have a 2001 Chevy Silverado 1500 LS 4x4 Z71 with the 5.3Lmotor. I was throwing around the idea of putting a true dual exhaust on it formultiple reasons. Fuel economy, hp, torque, and it just don’t sound loud enoughfor me. I want to replace the exhaust manifolds and put on some high flowheaders. I would like to know if it is worth spending the money to get the longheaders instead of the shortys, and how much of a pain it would be to installthem. Also I would like to know what the best way to set up trueduel exhaust. I’ve seen multiple different setups but don’t know what is thebest way to set them up.
