good day motorized bicycle gear heads, firstly it is true this is louder than your drill sargent, but people the power gains esp over flexable exhaust is crazy flex poopoo style held bike back badly and we all know factory pipe just dangeling down there waiting to ruin your day, its true most time either snaps studs or cause crash. now heres the trick replace factory with this remove allen bolt from clutch cover dig up same style thread bolt but a lil longer bolt up to cover with welded tab. remember that factory pipe sling it into vice cut about 2in from end. now with pipe still in vice heat evd withtorch straighten out as best as able slide that baby into end of this exhaust should fit snuggly use factory clamp to rig up stable mount to rear of bike and boom all the power from this awesome ppipe with no angry neighbors. forgot to mention this version imo is by far best one reason is its 2 piece so its more adjustable than solid versions and safer on you and your mmotor mounts reason is were its spring tension held together it is able if needed to flex and move instead of tearing away yourexhaust studs and ruining your ride and day. oh and its cheap ompared to most other restrictive flow pipes with its resonance chamber bike will be peppy and happy. what got to lose sellers got 30 day whateer warranty refund or replace cant beat it if dont like it return it and buy a diff. thanks stay safe out there,

I am running a Chinese YD100, exhaust sounded very loud and gave more power to the engine. would recommend it being sold as standard exhaust in kits to add power to all engines.

It actually worked great. Added more power. But ended up being way way to loud for my needs and neighborhood. Was great price. Fit very well. But just to loud. I'll give it to a family member who doesn't live in a big neighborhood. I would say 7/10 if it wasn't so loud. Very well buily though. Doesn't seem to have any fitment problems on a 26inch bike

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.

Were it attached to engine on the side mount broke. I use hose clamps to hold it together But it definitely opens it up once you lean out the motor will gain top end loose bottom super load. Warning louder than most of this style.i wouldn't buy it again I ran for 2 months with it broke. Put stock exhaust back on sold the bike. It was fun before it broke and my bike is everything new and tight so it's not like it was jumping around. It's just really thin

Easy install. Just had to make a bracket to secure to the drive cover. Noticable power increase.

Expect very high db, Like at a pro drag event, where you use earplugs. Designed for performance, it is a chamber exhaust. Upon closer inspection, it is all single wall construction. I ordered a muffler for mine out of consideration of noise pollution and my (and others) aural health. Cheers, speed freaks!

It came missing a bolt to attach it to the engine (stock is to short), and no gasket between the manifold and muffler. Otherwise it fit fine, and bolted on easy. Use lock tight, though. Added power, and definitely some noise! Kind of like riding a chainsaw. I might add a wrap to protect my leg, but you'd only make that mistake once 😁.
