Whenever I accelerate or slow down, the exhaust pops. Not quite a backfire, but noticeable. Doesn’t matter if it’s warmed up after riding a while or just starting off. Just finished up the Southern Exposure HOG ride of over 4,700 miles, so I rode in lots of different elevations, temperatures, fuel options, etc. and it did it the whole time. I found out it even does it in a Tropical Storm named Cindy, but that’s another story.
I’ve got E Series exhaust, Sport pipe headers (no cat) and the PowerVIsion tuner, but I can’t get it to stop popping.
Any ideas?
