It finally came! After almost two weeks the UPS man brought my pocket bike pipe! Opened the box and had no intention of working on the bike tonight but the more I looked at the pipe the more the bike was calling me to install it. Started out cutting the expansion chamber off and had every intention of installing it like a SBP kit but I didn't like the idea of losing my kickstand and I couldn't figure out a way that it wouldn't interfere with the crank arm so I flipped the headpipe around, laid the expansion chamber along the frame and BINGO I really liked it! Couple of tack welds and my attention was drawn to the muffler, I kind of liked how it was pointing down but the crank hit it so out came the angle grinder. I toyed with the idea of cutting the curve off the original headpipe but I looked inside of the muffler and didn't like the idea. I'm not a big fan of glasspacks on little engines, oh sure I have them on my trucks but they sound cool on them. Then I thought, "I went through all that work opening up my original muffler a few weeks ago it'd be a shame to toss it aside" so I hacked off the mounting flange, a few inches of pipe and BINGO again! Now my thoughts turned to how to support it, I looked around and there was the pocket bike mount that was the first thing I cut off laying on the floor. A little trimming with the angle grinder, a little bending with the hammer and I welded it to the original muffler then I used a spare coaster brake strap to clamp it to the frame. Only downside is I'm going to have to wrap the thing in header tape because I felt my thigh brush the expansion chamber a few times while pedaling so I have to get that done before spring or no riding in shorts! Does it work? HECK YEA! I could definatly feel it when the motor "came on" the pipe. The exhaust has actually gotten quieter with it, the only difference I notice is the tinny ping from the expansion chamber, kind of sounds like a quiet dirt bike now. The second picture is all that's left over.
