I read that a lot of you guys have put these on your cars. Is this a bolt on x-pipe that clamps to the cut y-pipe coming from the cats to the mid-pipes from a gt? or is this something that you need to weld and do other things to the stock exhaust? Thanx

Only kits that are bolt ons are kits like the JBA and Magnaflow. However, a lot of people have gotten GT pipes, mufflers and hangers with minimal fabbing. The only fabbing was with the H pipe. But its a cost effective solution for many. I dyno'd a X vs. a Y and the X showed a 2HP gain which is arguable on a dynojet.
