I do visit Limerock, the Glen and Circuit Mont Tremblant for track days during the summer and don't want to run afoul of their sound limits. Based on your post and some of the others, it sounds (pardon) like the bypass doesn't increase the decibels too much? Michael

Do you find the sport cats lower the sound that much? I'd be curious since it's so easy to swap if you or someone knew the actual dB sound delta between the sport cats and the catless Xpipe. Did you ever upload a video?

Thanks
