Nope. But from what I read comp exhaust donít have resonators. So you can do that to yours and do a resonator delete and it will enhance the sound. I am doing that next since I have the stock exhaust.

wait. okay so the comp pack cars dont have resonators.

but the mufflers are the same? so if i buy a comp muffler and put it on my car all that will change is the tips will be black? no sound change?
