Our Supercup Exhaust System is a loud and aggressive performance exhaust system designed with track use in mind. This system is a lot lighter than the factory GT3 system and flows much better.
The Supercup Exhaust System is a straight through system that brings out the full flat 6 snarl. It is significantly louder than our Maxflo Exhaust option, but if you're looking for a very aggressive exhaust note this is the system for you!

Just got this system put on my 2003 GT3 this past weekend. My only complaint is that I didn't do this sooner! Absolutely love it. Can't even imagine going back to a stock exhaust at this point. In addition to the awesome sound, I can certainly feel a slight boost in power as well. May just be my butt-dyno speaking, but even if I lost power I wouldn't care. The sound is so worth it!
