RedSVT, reread my comment - I am talking about the Contour application that we have available from SHM. Agree (based on my modest car knowlege) with the general statement "properly designed, equal length, long tube headers boost torque". But again, I gave 3 dyno examples, 2 cases of modest or no tourque gain with SHM headers, the 3rd gained tourque only after a custom burn chip. But could he have gained with the custom burn chip WITHOUT the headers??? This is the control experiment.
Am I wrong for being a bit skeptical about big torque claims for SHM headers?? I am a scientist and I like data. I enjoy speculation and hypothesising but must ultimately deal with proof. Sometimes the data goes against conventional wisdom. This means you eliminate variables and confirm results to find the truth (sounds a bit X-fileish doesnt it). This is what I believe the product manufacturers should be doing for us.
