RE: exhust for LRP
You can use any header on a BUKU. I use a lst2 header with a 3 spring connection, but a coupler style header works fine as well. I used to run a LST2 pipe for many gallons. LST2 pipe while better than the stock pipe , is not that good of a pipe. Im not so sure why so many people recommend the pipe. It's not that great. If money is no big deal get the jp3 or buku. The buku is not ROAR legal though, just in case you might race in ROAR sanctioned events.
