Hey guys, as everyone I'm needing imput. I am running a 107" in a 04 SE. I'm going to be taking the bike to a pro tuner in Joplin Mo. I was talking to him by phone and he asked what exhaust I was running. I am running a thundeheader now. He told me that I need to lose the pipe and try a Bassani road rage or a d&d fatcat. as the thunder header was hurting my low end tq. the bike puts out 115hp and 130 tq on a good day. Yes it does have a dip in the low end you can see on the dyno sheet. I'm looking for feed back on either of these two pipes, I know everyone has a opinion about what pipes to use, so I'm all ears. Both of these pipes are fairly expensive, also wondering if the gains if any would be worth the money. Am I right in thinking that all pipes in the 2 into 1 catagory are with in 1 to 5 hp of each other. Any way anyone with thougts ideas or a better pipe they know of, I'm listening.. thanks D.
