More Sound. More Power. No Drone.Are you looking for more sound out of your 997/991 GT3 without sacrificing street drivability? Look no further than the TPC Racing Active Side Muffler Bypass pipe. It provides cup car sound and performance when you want it, while eliminating unwanted cabin drone and excessive noise in normal street conditions. All this while improving performance and handling.
How it worksUsing a factory-style actuator-controlled valve, the TPC Racing Active Side Muffler Bypass System provides cup car sound and performance in higher rpm/higher load ranges, while eliminating unwanted cabin drone and excessive noise. Its lightweight design saves 40 lbs from the OEM side mufflers, resulting in improved handling. Better exhaust flow management allows for increased torque between 2,600 and 5,600 rpm, as well as increased horsepower between 5-8,250 rpm.

Weight Reduction from OEM • Factory-Style Actuator-Controlled valve • Metal Flex Joint for Easy Installation/Proper Fitment • Metal Flex Joint Reduces Chance of Center Muffler Fatigue • Machined/Fabricated In-House • Each Unit is Handmade in the USA • Stainless Steel Construction with Brush Finish

I just want to sincerely thank Tom and Harris for taking such great care of my car. I have been searching for the right shop and I have found the one that I will build a long term relationship with. It was so much fun at the track with Harris and I appreciated all of his guidance. Can’t wait for 2018!
Elite group of people, especially Tom and Harris!Thank you so much for your dedication and devotion to your clients. I have found my shop for life!!!
Awesome tuning by TPC!!! They really invested in the development of the mid-pipe to make it all come together w/ custom tune. Can't wait for the TPC intake goodies to become available.
Thanks to Mike Levitas and TPC Racing, I had one of those special days that will stay with me forever today.
I have the Stage 2 suspension on an '05 Boxster S and can testify that it transforms the car into beautiful, neutral handling bliss on the track without sacrificing any street driveablility. I run in the advanced group at MidAmerica, BIR, and Road America and everyone who's ridden with me comments on how well sorted the car is with TPC's suspension...
I love it. It's fast and reliable. The turbo has been installed for over six years without any issues. I've heard people bolt on 10k worth with minimal gains. I haven't heard anyone with the TPC turbo system regret their decision.
40k on my Stage 3 Plus TPC Racing Turbo Kit! Porsche performance equal to their win in the Rolex 24 Hours At Daytona! The TPC team excels in all aspects of improving the performance of and maintaining the car. I have been a customer for eight years now, and I give them the highest of recommendations. I can stongly say that they have improved my car so that I experience the most--and perhaps best--when driving my Porsche. A reputation considered by many in aftermarket and motorsports industries to be true experts and professionals. Coupled with DSC Tractive, other suspension, brake, and aero enhancements...Wow! Miles of smiles!
I have a stage 2. Installed summer of '13. Has about 8k miles on it, 90% track use. Zero turbo related problems to date. The TPC kit is quality stuff, the key is in the install.
