So I was poking around ebay today and found this. Does anyone know if it would work on ours?

umm....tough to say from pictures but very likely it will still need some modifications. The odds of finding an exhaust that bolt right are really really low. This does look like a good starting point though.

cutting & welding isn't that big a deal for me. i was just wondering if this would be a good alternative to the technigas option. as it looks like it might fit a bit better?

Of the two exhausts, I think the Tecnigas one would be easier if you're just trying to get something to work, but if you want it to look cleaner and perhaps not cut into the body panel then this one is likely better.

With the tecnigas, all I had to do was cut off the flange where it mounts to the cylinder and then weld on the stock flange at the correct angle. I did angle the end of the pipe a bit, but I didn't do any bending or major cutting to the pipe so it was quite easy. I did cut down the metal plate that mounts the expansion chamber to the engine but I just used an angle grinder for this and then I drilled new holes in it for the bolts at the engine case.

With this exhaust you've linked too, you might have to cut it shorter to make it look good, and that would change the performance characterists of this pipe. One concern I have with this pipe is how well it will perform. The tecnigas pipe I used was intended for bored out 70cc Zuma's, so at 80cc my Beluga wasn't far off. This pipe seems intended for 50cc's, so this might restrict the flow somewhat.

I'm sure you could make this work and look beautiful. I just hope it performs awesome for you and I'm a bit nervous about that.

Drag bike certainly not...but a peppy scooter is possible. My CV80 was way faster when I did my exhaust and carb and that make it a lot more fun to ride (and a lot less fun to put gas in). Ripping along at 50 or 60mph on those tiny tires with the crappy suspension was a real blast. My exhaust really made this scooter come alive in the 65-80km/hr range (40-50mph) with the stock gearing.

thats what I was thinking I wondered if the expansion chamber was a bit too small for the size of the engine. Thanks for the insight.

Hey guys and gals, Im new to this so bare with me ( and my poor spelling). A few months ago I purchased an 83 cv80 that ran, poorly, with the wrong carb. I replaced it with a 85 cv80 carb (thinking at the time it was for an 83 because thats what the listing on ebay said it was), got it on and running stong. Now to the point at hand, I've been reading the postings on the forum here and saw that I needed to upgrade the exhaust. I havent been able to find an 85 exhaust on ebay but the other day I was at northern tool and hydrolic and saw this little scooter and couldnt help but NOTICE the exhaust. heres a link of what it looks like it says its for a 50cc scooter but what do you think. It looks bigger than the little thing I have on mine now. Does anybody have any suggestions on this. Oh and it looks like it would need very little moding done to make it fit.

i think that even if it didnt fit right at first u could heat and tweek it in to place. it looks a bit long so youd have to check the fender clearance.
good find. good price to. note: exhaust off an 85 wont do you and good.
