I've recently just got my new 2017 camaro RS, and the exhaust was way to weak for me. I did little bit of research trying to find the most aggressive axle-back that's out there. So far the best ones I've found are MRT Version 1 axle-back and Flowmaster American Thunder axle-back. I live in Texas so muffler is required

. I don't really mind the drone and I'm trying to look for loudest and most aggressive axle-back with muffler that is currently available. It would be great if you guys could help out

thanks.
