Hi, I have a 2015 Ultra Limited with the Fullsac DX headpipe, Cobra PowerFlow muffulers, with a PowerVision tuner and a custom dyno map. Bike runs awesome, but I noticed the tips of my left muffler looks like it gets more exhaust flow going through it, as just the tip turns blue from the heat, vs the right pipe does not turn blue. Is this normal or does it seem unbalanced exhaust flow? Do the stock headpipe and mufflers do this too, or is it just my configuration? Thoughts welcome.

Thanks,
Gerry
