Check the links below. Seems a quick and easy way to overcome the lean condition snatchiness induced by emission regs.
I did purchace and install, I needed to corrected lean condition as Callumity quoted. I had installed Remus exhaust which made bird run hotter and also backfire excessively.. BP did help with those issues...but not completely. Still experiencing backfire occasionally, mostly in hotter weather...but all bike backfire once in a while. Overall much happier with results. Also tighten all exhaust conections...also helpful with backfire conditons.
Yea,I,m not going with a pipe,just removing CAT and getting a freer flowing filter. I think it would help. JJ
