The sound is great. The best thing is the weight. Weight saving of 15 pounds on our cars is great. The stock exhaust and even the performance exhaust weigh a lot for our cars.
Also, I wonder how the back pressure will be if you run Catless headers. I know that is one problem with our cars if you run headers you need alittle back pressure to get you off the line.
