Yes, it definitly did! I was all stock except for a K&N filter which came with the bike when I bought it. The Toomey was the only other performance mod I did to it and I can honestly say, it was a night and day difference. It is more of a mid-top range pipe, but I mostly ride tight/slow trails and have had no problems with it. It is pretty loud though, I don't know if you have any neighbors, but you may wanna take that into consideration beforehand. Feel free to ask any questions, I'll try to help out the best I can!
