If you guys seriously want a LOUD exhaust that doesnt sound like a POS pickup truck, here's the trick. Get yourself a typical offroad H pipe, and your typical 2 chamber Flowmasters. Take the flows, and cut the back half off, up to the back plate of the first chamber...if you've ever seen a cross section of a flowmaster then that'll make sense. You're basically creating home made single chamber Flowmasters. You won't need dumps since the back of the muffler is pretty much open. It'll be loud like a racecar, but retain that deep growl that Flowmasters are good for. If you want a more raspy, rippy sound, use an X pipe instead of H pipe. Fair warning though, the police arent real big on this setup...it's best for track only cars.
