This exhaust is ok for performance but extremely loud. Use ear plugs. I suggest adding a muffler on the end.

Had no fitting issues with this pipe. The workmanship is good and so are the welds. For those that say the spring mounts are welded out of alignment it may be that it was intended to pull on an angle in opposite directions as it works fine. Sure is hard to get the springs on. Better eat your Wheaties. The work I did to mount it was file the mounting flange flat and grind out just a bit of the weld to clear for the screw heads with washer. I made and aluminum 3/8 rod with 6mm stud in each end and screwed one side as a clutch cover bolt and made it longer to but a lock nut on the back. The other end is a washer, a rubber washer, the bracket then another rubber washer , steel washer and lock nut. I had to drill and file another hole in the bracket to line up with the stud. I have it mounted on a test bike that I test out ported motors. I can't comment on peak performance as I switch from gutted stock pipes and various carb combos. Like stock NT, a modified NT with key holed bore. A Bofang and a cheap HP carb. The key holed NT is taking a 3/8 end mill and cutting the top of the carb bore through to elongate it to increase the volume and flow. Just cut up to the point of your intake diameter on top. I will be fitting a screw in lawnmower muffler to the end of this pipe to easily remove and install at will. For the price I payed under 35.00 and I did not have to bend it to fit it is sure worth it.

Why did you pick this product vs others?: I was looking for an economy pipe for my motorized bike and this one looked good. Installing it was super easy. The springs give the pipe some needed movement, these motors vibrate like crazy. I'm still working on tuning it. I've got it on a 100cc motor and I have great low end power but it won't rev like it should and theres no power on the top end. I've tried jetting up and down and switched carbs and did the jet thing again. Seems to work best with a smaller jet (65) but still don't have the top end speed. It's a work in progress. More to come later.

Very well made .. I'm impressed for the money spent. Like stated it's loud until I modified stock muffler and joined it with expansion exhaust.. what a difference it has made for this bike.. the motor was bougie lacked any real power now with this new exhaust 5 times the power and looks really cool.. money well spent ... the product is well made good looking I will be buying another for my 3rd bike which is a 100cc can't wait to feel the power increase on it.. get one it's a game changer for the 80cc. You won't be disappointed

Light scratching on arrival. Only noticed after taking off bubble wrap, so it was likely during preperation for shipping or during manufacture. Other than scratches product finish looked good. Provided gasket had a chunk missing out of it. Welds look like hammered dog crap but they should hold. product fit well but it was an absolute punch in the scrote to get the springs on, however that tells me it should stay in place in rough conditions. A good option for people wanting an expansion tank with an odd angle to go around. It went on Schwinn 100th anniversary edition beach cruiser.

My son loves it! I did notice a small increase in power but not substantial. It sounds super loud and looks good. My teen loves it I prefer the stock pipe but for him five stars!
