normally everyone would be telling you that your thread is going to get closed and that there is a special section for this stuff but I think your car is just to badass and nobody can bring themselves to do it.
I had flows with my offroad X and it sounded like a jet, but not in a good way. My ears would ring everytime I drove the car. I think that the fact that it was catless was the reason it was SO loud. I switched to a straight through style muffler and it sounds much better IMO. With cats though it may not be too bad. It was a different type of sound, it was just too damaging to my hearing to keep it!
