hey i didnt know how to search for this but i have an aftermarket exhaust (scorpion) on my 05 636...it pops a little bit when downshifting or slowing but i was wondering if i were to get a K&N air filter as well would that increase the popping if i dont get a fuel management system?

I read somewhere here that you should keep the stock filter. KandN with make is worse with more air to the fuel mix.
I have the scorpion also. pops sometimes when coming down off high rpms. doesnt bother me and the bike still runs better than ever did.

ok cool i guess ill just get a new stock filter

edit: any other input?

If your going to get a power commander then go for the K&N but if not then leave it stock.

ok cool thanks for the advice...i wish PCs werent so expensive..

Get this and alleviate MOST of your popping as the air fliter is not causing the problem...Also the Stock filter makes the same amount of RWHP as the K&N, just not reusable though.




If you can't make your own you can buy them here.
