Before I got rid of my 87 250r ,I had two pipes for it. One was a Esr trx11(my motor had a pretty good build on it to use that pipe, port and polish ext) and the other was an Lrd. When I trail rode I used the lrd and used the esr for about 90% of the time. Both were goods pipes but if you are going to be trail riding alot dont get an esr trx11. I would get an lrd if I was you
