Check the angle on it good. The Japanese version of the AF05 (AF06 or AF09??), has a different angle on the exhaust outlet on the cylinder. Probably about a 30 degree difference if I remember correctly. It would probably work OK, but be prepared for possibly having to hack the header a bit to angle it correctly and reweld. Hopefully I am mistaken.

I guess it beats nothing!They spent a lot of time and effort snaking the body all around(why??),then put a crappy/cheap/poor performing telescoping head pipe on it...

then put a crappy/cheap/poor performing telescoping head pipe on it... That was the first thing i noticed too. One of the trademarks of a cheap pipe. Just a bunch of stepped pipes welded together. I always cringe when i see headers like that. The rest of the pipe looks kinda nice i guess. Welds look good and they clearly put a lot of time in fabricating this pipe with all those segments. But the first bend is kinda sharp which i don't really like. It's hard to judge the shape of the pipe but i think it's alright. Ratio's between diffuser and baffle angle and belly diameter don't look that much off. I bet it sounds pingy.

good to know. thank you for everyone's input. right now im current high bidder at 60$ plus fees. if someone out bids me so be it I guess. funny thing is I made a pipe out of a spree muffler and a similar looking header cut and from an 86' nb50 pipe. I cut a section out of the nbb50 mufflers innards. it doesn't perform as well as my drilled nq50 muffler. its header is stepped and a lot shorter. gave me a higher rpm powerband which is what I was after. like I said in another post 2t exhaust is one thing I haven't even dug too far into. as for fitment I have a jdm af05e (af09) exhaust on my us af05e (aero50) cylinder right now. no problems. and my homemade (from US parts for my US cylinder) on one of my jdm tact af09/05e engines. no problem with any of them or my italkit bbk. so if this pipe isn't my best choice. what do yall think of the mlm af05e pipe or the SSS 50$ chamber attached to a different header? either of them viable options? theres a simonini Peugeot pipe that looks like itll fit too. that might be another option. would love to hear yalls thoughts. thanks

harley...if you do not mind a bit of cutting and fitting and are looking for a temporary fix, try to find a KTM 50SX pipe. Not ideal, but we have played with a few clone pipes like that with decent results. Just a stocker from fleabay, dirt cheap. It won't fit, but if you are good with mild welding, not hard to cut and rotate a weld or two.
We did one on a Gyro X that swept up like the dirt bike...it did well, but ate fuel. I think the KTM 50's were 7-8 hp? Just guessing.

thanks TG. ill keep a lookout for one. I don't have a problem spending up to 200-225ish for a pipe. I also have no problem fabricating something. I just cant see spending 300-400$ on one. I don't have that much in the scooter, motor, and BBK. lol. plus I enjoy tinkering and get pride out of the "I made this". I like the looks of that mlm elite pipe. itll be going on a 7 port with W exhaust port 46mm aluminum bbk. heres the pipe that I made knowing very little other than the longer the pipe the lower the power band. shorter= higher. and im not sure that's even completely correct... lol

Wild build youve got there harley!We gotta get you 'tuned' into the 2 stroke way,,Ive never been around Honda scoots,but Ive seen that Kymco built scoots for Honda,then produced their own,that gives you more searches for stuff,Yamaha also built a vertical cylinder scoot,,I'd think any of those pipes could be adapted(with welding)to produce a decent pipe,gotta keep in mind the RPM capability of your cylinder/build..Hopefully some of the Honda/Kymco/Yamaha dudes will chime in on their opinion!

thanks 190! ive seen those on there. fleabay also has a similarly priced and looking dio pipe on there that ive wondered about for cannibalism or for an AF18 I have sitting on the shelf waiting for a body needing a new heart. what makes this a good candidate? what do you think its powerband rpm might be? what should I be looking for? have you seen the motion left moped edm elite pipe I posted a pic of it. has a 25mm header and it start transitioning to the chamber close to the flange. is this a good option? what kind of powerband might it have? thanks for all the info that's being given. I'm always ready to learn a thing or 3! as for my chopping spree, it started life with me getting for free not running. had no seat and the only fairings left on it was the lower handlebar piece and a cracked broken front fender. so I made her my own with extra parts I had laying around. its only a 50cc right now but with a mildly ported rejetted stock carb and a dio variator koso weights, springs it'll pull the front tire up on command and does 52 on gps. its light as hell front tire is a honda express 14". with black light under glow lights from front to back. its fun to ride and I guaranty its the only one like it in town.

Harley,I didnt even think to look for a Honda pipe!Here is one; www.ebay.com/itm/Complet-Exhaust-Muffler-System-Pipe-For-Honda-DIO50-AF18-AF24-AF27-AF28-30-Steel/112951348768?hash=item1a4c6cce20%3Ag%3AfFIAAOSwMGha2cny&_sacat=0&_nkw=honda+dio+exhaust&_from=R40&rt=nc&_trksid=p2060353.m570.l1313.TR2.TRC1.A0.H0.Xhonda+dio+exhaust.TRS0.TSS0That black pipe you posted looks like poo,,A pipe should have smooth transitions between the joints,a short pipe is high RPM,long for lower revs..Without having actual dimensions,its just a WAG(wild arse guess),the two I posted have had OK reviews,they are NOT going to perform like a well designed pipe,but a heck of a lot better than a muffler with no chamber.. Bet that ride does get the front end light,once youve got some power in it,hold on!!

Haha...all of the above. I have an early Gyro Honda. AF01E. many think there are no pipes for it. Only true if you want to keep body work. Any Dio pipe can work. Yes, some have crazy port exits. Who cares? I have cut and welded my share. My Dio experience? Mild pipes that produce OK sound. My Honda with KTM pipes? WOW power. Hard to mount unless you can cut and weld. Fun!
BTW harley...my own pipe design came from numbers from 190mech above. Mid range monster. 49cc crazed but evolving pipe. It doesn't wheely...yet.

so I can get that ebay pipe for 70$ theyre local here in LA. or theres a guy here in offer up asking 125 for this pipe its new for an Aprilia sr50. which would be a better starting point? im sure the yasuni pipe is better quality but it looks like its for a horizontal. worse case scenario, I do have a honda express that needs an upgrade!! lol

I'd go for the $70 pipe,the Yasuni would be a bunch of work to fit,or buy both and have fun!

lol!! youre awesome, 190!!! I like your style! thank you for all the info and guidance. im supposed to meet him for sure sunday, maybe tomorrow if he has time. what size header would be optimal, or would you need more info on cylinder? I need to make a port map for that cylinder. I have some for the stock af05 US cyl, af05 jdm cyl, spree cyl, nc50 cyl, stock ab07 cyl, just need to find time to sit down, measure and record all the #s and post pics on here. so every one has them!
