Progress has been made. I wrapped the pipe with header wrap. 2" wrap with about 1" overlap, so pretty much doubled up. Stock silence from an 86/6 LT250r stuffed on the FMF midpipe(silencer cut off). Before I wrapped the main pipe is was still way too loud, mostly the pipe noise associated with aftermarket pipes. After wrapping with the header wrap it was like nite and day. Veay quiet, compared to before to say the least. I only ran it a couple seconds, the schmeg I used to seal the pipe to cylinder flange was not fully cured. I believe this set up will be quiet enough to satitsfy Mitch the **** warden. Final tunning will have to be done once it gets colder. I switched pilot jets from a 40 to a 30 for idling purposes, 85 out now compared to 0 in the winter. Header wrap is more than half the price on ebay than the local parts store by the way.
