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 works

Using 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.

Features

• 40 lb. 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

At TPC Racing, product development never ends. We are always looking for new ways to improve our already fantastic system. In our quest for more power from our 997Turbo RSx program, we began experimenting with different headers, and found a setup that greatly improved exhaust flow, yielding significant improvements to both the low and mid-range performance. With the addition of the RSx Headers, the TPC Racing 775RSx packs an even bigger punch than before! Performance in the mid-range has been boosted by an amazing 80whp and nearly 100lb/ft of torque! The TPC Racing RSx Headers definitely take the 775RSx system to the next level! This increase in performance has boosted the 775RSx's numbers to a whopping 775HP*** and a mind-bending 770lb/ft*** of TORQUE!!       * prices subject to change ** Output will vary between vehicles *** All WHP(wheel horsepower) figures are determined using a Dynojet Reseach Inc., 224x RWD dynomometer. All BHP (crank/brake horsepower) figures are estimated.
