The best 2 ways to fix a bent 2 stroke dirt bike expansion chamber pipe.

In this video, I cover two ways to straighten an expansion chamber on a 2 stroke pipe. One is the most common way by bending the gooseneck while most dirt bike riders miss the pushed in area of the entire down tube of the chamber.
Tips
- Use a press but don't use too much pressure or you will squish the pipe
- Make sure you get great alignment between the exhaust port and pipe flange
- After aligning the exhaust port and flange, confirm the corrected fitment on frame tabs
- Use a bead of high temp silicon on the lip of the flange
