Sounds AMAZING! I love that high pitch wail up top. I was hoping you guys would come to the party with an exhaust for the 991GT3. ETA?

 

Looking like 2-3 weeks before we have them on the shelf. Here are some dynos comparing a stock car, the Clubsport Exhaust, and the full system with Clubsport Headers:



We play with a lot of really cool cars around here, and while many of them are unique...you sometimes get to the point where seeing something crazy is 'another normal day at work'. The first day we got the GT3 back with this system installed, even our engine builder John Bray who is a no-nonsense, down to work kind of guy was outside listening to it run around the block with a big grin on his face.

 

Looking at picking up a 2015 GT3 so I might just have to buy the exhaust Sam.

 

Did this dyno result require ecu tuning in addition to the hardware?

 

Completely stock ECU and 91 octane. We will be developing an ECU tune specifically for the exhaust and headers sometime in the future, stay tuned!

 

They are fantastic cars, let me know if you pick one up and we'll help get a system on there .

 

Very nice! I will stay tuned. The headers will likely not be CARB approved though, right?

 

Correct, not likely to get CARB approval for aftermarket cats.
