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.
