If you're decel-popping regardless of tune, you likely have an exhaust leak.

In my case I flashed the proper map, just in case. The PO said that it was popping on decel since the day they installed the Jardine (and flashed the ECM) and everyone I have mentioned that to says it is the can. He sent me the original muffler at no cost (even paid for shipping). I do have a leak where the can mounts to the header, with springs no less, and I have been trying to fix that before I swap it out. I am going to have to pull it and apply high temp sealer. Hopefully soon, if the rains let up.

Why would anyone use springs at that point? I see them on sport bike exhausts all the time, but never felt they sealed anything all that well. Am I missing something?

Getting cage crazy. It's been too cold and/or wet to ride and I'm going NUTZ!
