Dynojet results for the USP Motorsports 997 GT2 Race Exhaust - +52 horsepower at the wheels
Nice numbers here provided on a Dynojet by USP Motorsports. This 997 GT2 features the USP Motorsports Race Exhaust system made out of 304 stainless steel mandrel bent piping with Burns stainless steel mufflers. The change in tone versus the stock exhaust is immediately noticeable with a much deeper growl and some of that audible turbocharger whistle although the sound is not exactly pretty. It's more of a rough growl.
What about the gains? USP Motorsports claims a gain of 52 horsepower at the wheels and 65 pound-feet of torque at the wheels although they did not post a graph to corroborate their claims. Why put the car on a Dynojet and then not post the graph? What's the point? The peak gains are impressive but buyers certainly are interested in the whole picture throughout the powerband.
