Hi Michael,
I was the only bidder on a pair of new Speedmaster tapered long pipes. The starting bid was $0.99. I watched for 5 days and bid $45 with 20 seconds left. I got them for $0.99+$21.40 shipping. I ground out the end plate with a rotary file in a drill motor, then removed the little tube and the next plate in. All other plates throughout, got a 3/4" hole drilled with the same rotary file. Sounds great and breathes well.
Ride Safe.
Dennis
