YOSAYUSA Motorcycle Exhaust Pipe System for GY6 Engine 125cc 150cc Scooter Moped ATV Header Muffler Baffle Silencer

Excellent Tone. You won't remove the baffle after you have satisfied your curiosity. Too loud and ruins the tone. That being said, the 5mm bolt will never be capable of not vibrating out. Period! So, use high tensile strength liquid steel. Picture shows me not thinking first. No liquid steel need show. Apply to outer surface of baffle, press fit into exhaust, cure 24 hours. This being greatly preferred to my method of inserting the baffle first and then mudding up my beautiful exhaust system. Gerr! Now as to the mounting Bracket picture. Most of us have had to grind clearance for the oil dip stick in the area indicated. No strength lost to the bracket. Good looking exhaust. The exhaust header pipe breaks into some awesome blues and purples. Filthy bike at the time of exposure but, the exhaust cleans up like new every time. It's a good buy.

Liked the looks and construction of this unit. Also sounds louder than stock with great tone but not too loud to be offensive .

Sorry if this sounds robotic but I'm cutting and pasting it to multiple places including my Amazon review & my FB group for this bike. This WILL fit a 150cc Super Hornet / Roma automatic Chinese motorcycle but there are some things to be aware of. I recommend reading all of this before swapping out the stock muffler. I'm not saying this is the best way it this is what worked for me.MUFFLER REPLACEMENT I recommend reading all of this before swapping out the stock muffler. I'm not saying this is the best way it this is what worked for me. Big thanks to Jason Saylor for guiding me in part of this . 1. Amazon requires someone is home to sign for it and gives the driver a passcode that they email in am if delivery .2. The header pipe will change rainbow colors.2.5 You will most likely need to grind off the ends of the dipstick grip ( the thing you turn to pull it out ) otherwise it's probably going to hit the little loop where the springs go.3. You need to save the nuts that attach a muffler pipe under the motorcycle4. You need to get a a tube of red, high temp gasket maker from any auto parts store or Amazon to paint on the end they attached under the bike, get the standard gasket ring also and lastly get a tube or black high temp gasket maker then squeeze a thin, 1" flat piece of this into wax paper and let set. You will cut it to size when it's cured after peeling off wax paper. This is going to go between the rear shock and muffler if a tiny edge is touching the muffler. It did by a millimeter for mine. It helps to have a friend pull the shock up as you slide it there. Watch your fingers and theirs. This stuff comes in handy for other things as well. 5. You're going to need to wipe your finger prints off everything before the first time you start the bike after install or the heat can permanently burn your finger prints in. Have the alcohol next to the motorcycle key so you don't forget.6. Get a tube of blue Loctite for all nuts, bolts and screws. You will need that extra grip due to these areas vibrating and you don't want anything coming lose.7. You will be inserting the pipe over the bottom frame of the bike and you're going to have to slow it in slowly at a specific angle to get it in. You do not need to take off any other parts. The nut closest to you is going to be too tight to get a socket wrench on there and hard to even get a socket wrench in due to the frame being in the way. You will need the smallest crescent wrench you can find. I could not secure it properly on the bottom with the right gasket set up or get outside nut on the right way without a motorcycle lift or smaller crescent wrench so I had to bring it to my mechanic to correct hat part of my install. The good news is I did not have to adjust my carb after install like you do sometimes.8. You're going to want to bend the band that will go over the muffler end tight so it wraps better. You're also going to want to Ziptie the two pieces of the band together tight at the top so it's not working against you are yorue trying to bolt it on.9. You're not going to be using the stock attachment for the band. It is going to ideally give about one inch over that.10. You're only going to need the little zig zag looking bracket it comes with not the longer wire looking black bar bracket. You're going to attach the al bracket to the left bolt of the muffler side of the bike that holds the carb and fender cover on. You're going to angle that brace up as much as you can with the left side but not in.11. The band is going to be about 2/3 of the way to the right of the muffler.12. You're going to put the pipe end on first then the muffler, pressing the two pieces tight together, next stick one of the sprinte between the end of the muffler and the part where the stock brace attached so you can train the muffler to maintain space as you tighten the band, next secure the band then the bottom spring then the top spring. The top spring is a hard stretch and the pulling will cause your bike to want to be pulled off the center stand so having a friend stand in front of the bike, holding the handle bars straight and pushing against the front the the bike as you stretch the top spring towards the front of the bike will be helpful.13.

Had no issues installing it at all had to improvise some to mount it didn't need to use bracket well worth the money had a smell first two days but went away after riding scooter continuously cause exhaust was new had to burn the smell out but was good afterwards, and it looks damn good.

Easy install for my Icebear Vision PMZ150-17. Bolt up the header pipe first, only snug the exhaust stud nuts then mount the muffler.You may need to slightly tweak the header pipe outboard for clearance for the muffler, hence the only snugged port nuts.Then mount the muffler and judge the clearance. Use the spacer from the stock exhaust to mount the muffler hanger to gain more clearance, you can use the open bolt hole on the existing bracket on the Scooter. You will need a longer bolt than is supplied with the kit with the spacer and hardware, like another half inch.The thread is the same, it just needs to be longer.You will need to buy a Stainless bolt/washer and nut set for the hanger, and you will only need the supplied "Z" bracket, the welded big hanger is not needed.Sounds good, and now the Cars can hear you unlike the stock exhaust.. I love that the header pipe and the muffler turn hues of Purple, Gold and blue after being heated while running it.I'm pretty happy with it, if it's bit loud for you add some steel wool to the removable baffle to quiet it down.That's not my picture in my review, but you get the idea.
