Just finished up and finalized the new header. Finally got what I was after in the low end department.
This chart is a 107, TTS100 cams, MX Pipe, 1.75 VS 2.0 baffles. The smaller 1.75 have more TQ on the early hit and are the quietest. For me this is perfect. The 2.0 baffle has slightly more mid range and more rumble. Honestly splitting hairs.
Those that are going to keep the stock headpipe, you will need the larger 2.25 baffles to get some rumble out of it.
Adding the screens and Techmat blankets smooth the sound and drop a DB or two. If you like a harsher more aggressive sound, leave the can empty. There is no power difference either way.
And yes, that is 100 Ft pounds at 1600 RPM.
The current trend with the M8 is clipping the dyno runs on the front side to hide the early TQ loss. You won't see that from us.
