My Supertrapp "Open end cap # 405-3046 came today.
FYI;The cone is stamped "FOR CLOSED COURSE COMPETITION USE ONLY", so it's gotta be louder AND faster right?!
This is a poor (indoor) shot of the 'Trapp w/ the used headpipe I got off ebay & coated. It wasn't just blue it was 'preyple':
I am hoping the supplied 8 disks will be about right for this and I can cork it back up if I need to w/ closed cap.
Still waiting for NOS carb.
FYI;from Supertrapp site, Harley 2:1 tuning:
"We do not suggest removing the muffler packing material to "get more noise". Removing the packing will result in a loss of power due to the sound waves not being absorbed into the material thus causing a restrictive wave in the core. The core was designed to flow with the packing installed, removing it will also have an effect on the jetting in most cases causing a lean condition.
Removing the closed end disc and running just the polished end cap with or without the discs will also cause the jetting to go lean and lose power. If you must have more noise, we suggest you get the optional 4 inch open end cap (p/n 405-3046) and run 9 discs. This set up has the same flow as the 20 discs and the closed end disc but it will add more noise."
