My mistake. I already have the Cat back installed. It's the complete kit. Pipes, mufflers, tips. What I'm looking for is a setrup to go between the engine and the cat back. but I still need to pass inspection, so I guess I need to keep the Cats in place. I'm looking at getting the XCalibrator 2 tuner and would like to do the mods before getting it dynoed.
thanks for the help
