Don't believe the hype?
The proof is in the numbers! We subjected our 96 3000GT to a battery of exhaust installation and dyno testing and have shared all the results in an FAQ article: 3SX NA Exhaust Dyno Testing. Here is the dyno graph comparing the "all stock" to "all 3SX" exhausts and showing the 20 hp gains at 6500 rpm.
This is the dyno video of the car with the full 3SX exhaust installed. Check out the 3SX NA Exhaust Dyno Testing for many more videos.
This is a much better video with the camera attached to the back of the car. It is a 96 Cali-spec car running the NEW 3SX Kooks NA Downpipe, 3SX Kooks High-Flow NA Cat, and THIS all new quad-tip full-stainless 3SX Catback Exhaust System!
