I have a 2001 rc51 equipped wit carbon fiber Two Brothers Racing exhaust. the cans are too loud for the development i'm livin in. the neighbors have complained and the management has threatened to evict me. I'm willing to trade my exhaust for the stock straight up. i'm also willing to trade the whole bike for something that's quieter, like a 750

I have stock exhaust from a 2003 i don't know if they're interchangeable or not but I'm up for it if they do. the came off the bike nearly from the showroom floor.

The SP1's use round exhaust ports while the SP2's use D-shaped exhaust ports.
The head pipes were shaped accordingly.
So you may used the SP1 pipes on an SP2, but not SP2 pipes on an SP1.

I have a stock set of pipes from a 2000 that I will trade you. PM sent, and heres a pic
