Default My new Pocket Bike Pipe

I ran out of patience and bought a pocket bike pipe. It's very similar to the SBP pipe. I cannot tell you enough what a difference this made. I can hit 30mph in less than a block. My best friend is a Millwright and very talented with his wire feed. If you don't have this luxury I highly recommend you go with the SBP pipe. This took us most of the day to do. The header took 4 cuts to get a good fit. I also cut the main pipe from the muffler and extended it 4" to give easy pedal/tire clearance. The difference is night and day. Huge torque boost plus the sound rocks. I just got home and haven't touched up the paint yet but I hope you like the pics.

Hey tylerlough, I cut and refitted the header section with no additional pipe to keep it the same length. It's maybe a 1/4" shorter from the cuts. I added about 4" between the pipe and the muffler section. It made the clearance for the tire and pedal alot easier. Back there it has little affect on the pipe. I used the same steel tubing I made my new intake from. My camera is dead when the battery charges I'll post another pic with the paint finished.

That's good that no additional curved pipe is needed. Now I need find someone to help me weld it back together.
