Nice Exhaust

Easy install and definitely added some extra power to my wife's TTR125. Had to rejet pilot, main and needle, but it runs great after doing that. Fit was excellent. Reasonably loud, but not that obnoxious.

2004 rm 250

Purchased with a new Turbine 2. Installation was a breeze, no issues except I recommend slightly longer springs than stock. If you don't have a spring tool, get one. Went to the track this last weekend, there is a noticeable power increase from low to top end. On top of all that, the bike sounds brand new. Thanks FMF.

Great price

Had to tap it in with a mallot slightly as its a tight fit in my FMF Factory 4 pipe. Take in mind that if your state has a strict noise ordinance, this does not muffle below the 94db threshold. It is, however, USFS approved and is very reasonably priced. I see some out there in excess of 100 bucks... LOL id cut a screen myself before I'd pay that. Overall it gets the job done at a very reasonable price through motorcycle superstore.
