Continuing our tradition of bringing together our racing heritage with our street performance parts, we recently developed a GMG WC-GT style center section for our GT3R. We were able to shave some weight and gain a couple horsepower.

Our GT3R now used our GMG Center Section in place of the mandated and homologated Porsche Muffler system.....I can't wait to let 'er rip this weekend!

Everything else on the car is SRO spec for PWC including the weight and restrictors....we want see how this car sounds as well as any top end gains over the stock muffler......

Installed the GMG center by pass about 10 days ago. I absolutely love it. Install was straight forward and it sounds and looks great. The most amazing aspect is how benign the sound is below 3500 with the valves closed. After that, it is like an F1 exhaust. Truthfully, no videos do justice to what it sounds like either inside the car or outside the car. Folks at GMG are great.
