Black finish Tecno Boss exhaust for the Tomos mopeds with the A3 and A35 engine. Will not fit the Revival or Streetmate.
28mm Internal diameter header allows for a higher top speed. Expect 5-10 mph gain over stock. Re-gear for even more.
Also will fit a Derbi Variant piston port engine with some minor mods.
*May have fitment issues on some early A3 models. You may need to get a set of pedal arms with more offset like the ones below.

It was a pretty easy install on my A35. I had to drill out the holes for a better fit, but after that she bolted right up. Added 5 mph to my stock ride, plus I got several compliments on it's look and sound after a quick ride around town.

Great for top end, will bring your speed up. I hit 50 with this and a the 26t/22t gearing, and a pretty broken engine in need of major transmission repair, but that was also downhill. Flat out hit aroundabout 45 before my rear exhaust mount cracked. Definitely recommend a 70cc kit to cope with the lack of bottom end, but without it just run stock gearing.
