How does a Stainless exhaust expanding .5mm over its entire length help maximize airflow?
Also, heat dissipation from the exhaust (in general) would actually hinder performance. When exhaust gasses stay hot, it improves the scavenging effect, increasing power.
Correct. That was a bit confusing. I think he had some things mixed up when I was explaining the expanding of the system to him and how the tips do stick out a little farther from the bumper on a hot exhaust. We try to keep our EGTs how throughout the exhaust system to provide for better exhaust velocity. Thanks for clarifying

My camera took a shit during the 3rd run so no video, but I have a pic from my cell phone on the results..RPI POWA! Thanks go out to JTranstudio for allowing me to tear up his dyno and rpi for making an exhaust that put out the powa. Ps. I'm still waiting for advertisement fees. Lol.
