Nah, I don't want to drill into those beautiful tips, plus getting the fit right seems like it'd be next to impossible due to the curvature of the inside of the tip. Btw, how does that even work to reduce the sound level?
The drone is only annoying at 2k rpm ish and then I actually think the powerloops could afford to be louder higher than that :P. Pretty satisfied with the exhaust setup right now.
