yup, i get the popping too on decel. I have the SE Stage 1 AC, remap from the dealer, and the shortshots with quiet baffles. I get a little bit of it. The dealer told me, as well as alot of folks on this here forum, that because of the shortness of the pipes, you're going to get some no matter what. I don't think its damaging the bike. Its the nature of the beast.

need more info... fuel pack? power commander? race tuner? what air cleaner? if you did pipes alone with no baffles you will probably need to free up some more air with a high flow air cleaner and some kind of fuel management..

alot is probably due to no baffles....my brothers bike did the same thing when we removed the baffles, so we put them back in and it cured alot of it.

I get very little decel popping since I installed the quiet baffles. Most of it goes away after the bike warms up. The quiet baffles soften the harsh tone with very little reduction in the sound volume. It's a good balance for me.
