Not sure why people seem down on the 2087 pipe. In the vids I've seen it looks to make good power, with a nice high screaming sound.. Just saw this for ex:

Sounds like a banshee..

Might finally break mine in this weekend if I can find a 15T clutch bell somewhere..(finally got a truggy roller for it..) Don't know what pipe though. Should have an 086 and 2058 arriving in mid-September.. For now I guess I'd try the 0801 or 053...
