Have not had any problems yet, but would like to have a little more low end and get rid of the wall it hits at about 35mph, top end is not a great concern, would just like to get to 50mph a little quicker.

The Supertrapp IDS quiet core added a lot of torque to my HO 500 motor but did hurt the top end some. A person I ride with put a FMF on his HO 500, it didn't add as much torque as the supertrapp but didn't hurt the top end from what I could tell. It may have improved the top end but I havn't ridden a stock HO in a long time so I can't make a good comparison. If you have a NON-EBS you could tighten the rear clutch spring and move up the shift wall. The cost of the parts needed is FREE! I've see a FMF on a magnum but I am not sure if the person just fitted it up but they don't list one. Supertrapp make pipes for everything.
