Finally put on my old exhaust axle back. I kept the pipe from the cat to the axle but it doesn't seem to make much of a difference. I lost a little power but the car is so much more quiet. I'm gonna keep it off until I get my turbo system. I also reved the car without any muffler on. All I can say is damn that is aggressive. I figure if I ever make my own cat back system I will make a straight pipe for the muffler section and do it Dodge SRT4 style for off road strip days. I only reved it to 3k and damn it was loud. The resonance of the garage also didn't help. That was my project for the weekend. Next weekend I'll be doing work on all four corners with the SS Brake lines. I'm also gonna be changing my STX fluid and radiator coolant
