The ultimate lightweight cat-back exhaust system for the 991 GT3 / GT3 RS saves 54lbs (24kg) off the rear of the vehicle and is perfect for competitive track use, high performance drivers education events, or aggressive street sound.
NOTE: This is a straight pipe, racing oriented exhaust system built to be light and make power. As a result, the volume level will be very high inside the vehicle.

I had this system installed on my 2016 GT3 RS and the sound is simply mindblowing. It is not for the faint of heart but if you really enjoy a raw, aggressive exhaust note this is the one to get. Biggest difference between stock system and even a center bypass vs. the lightweight competition exhaust is the nasty growl at low RPM's. The car has always sounded feral up high but now it finally sounds good down low too. Great job Fabspeed, would highly recommend.
I had my local shop install Fabspeed's Lightweight Competition exhaust on my '15 GT3, and I am absolutely blown away by the viscous sound that was hiding beneath the heavy and restrictive stock mufflers. In addition to the sound which takes the GT3 experience to an entirely different level, you can definitely feel an improvement in acceleration and handling from the weight reduction. This exhaust shaves a ton of weight off the car where it matters- the rear!
I would advise staying away from this particular system if the car is mainly street driven, as it is SUPER LOUD. For me though, I cannot get enough of it. Nothing but praise for the guys over at Fabspeed.
