I like loud pipes, and when I cut the baffles out it still wasn't loud enough. I had my brother ride my bike so I could hear it. When you are riding it it IS louder but from a distance it still sounded stock, just a small bit deeper. Soooo, I got to thinking and went to Home Depot for some tools.

I bought a 1" hole saw and a 12" drill extention and drilled two holes the the second baffle. Then slid the saw down the small tube and drilled a hole in the third baffle. Then went through the holes I drilled the the second baffle down to the third baffle and put two more holes in it. It really opened the bike up and man it is way louder but also sounds VERY good, deep and throaty. Not just my opinion though, several other sport-twin owners complement the sound and ask what brand of pipes I have. It is loud and will set off car alarms(definite coolness factor). But I believe in the theroy "loud pipes save lives" I have rode in a car next to my bike and you can feel it even with the window up. A friend of mine had an RC51 with Erion pipes and mine were quite a bit louder and just as deep sounding. I like it, but my opinion is the only one that counts for me. I figured that if I screwed up the pipes, there are plenty to be had on ebay.
