I ordered the exhaust and when it got here none of the displayed hardware was included. On top of that it didn’t fit and granted that’s my fault but i would have still liked to receive what I paid for. The welds were also boogered on there and something is rattling in the muffler. total junk.

Auf dem 1. Bild sind die Schrauben und dichtung zu sehen. Wenn mann (so wie ich) sich nur auf die Bilder verlässt, denkt mann das die zum Kauf dazu gehören. In der Beschreibung steht allerdings (was ich nicht gelesen habe) Lieferumfang 1 Auspuff. Bitte entweder die Bilder ändern oder die Sachen mit Anbietern. Ärgerlich deswegen nur 3 Sterne.

I knew from the get go i was going to have to modify this exhaust for my sons 49cc quad. So the quality is good enough to cut, weld, and grind on it. The little 49cc engine sounds nice with this muffler.

Great exhaust system for small performance engines. I used this on my 52/49cc (you never know with the cheap Chinese ones) engine swapped pocket bike. I put the engine I used in the review pictures. This exhaust system for almost perfectly after cutting the hanger off of it and this bike is very very small so that’s impressive. As you can tell by the custom engine mounts, I’m no welder or mechanic. So I could have made it fit with some more “custom” work but it is almost all the way on, very very minor exhaust leak. Build quality has been good so far, will update if that changes

I bought this pipe to put on a 66cc motor kit for a mountain bike.i had to cut the flange off and reposition and make a bracket. The expansion chamber is a little small but it made a difference in low to midrange power and sound on the stock engine. For the price it was well worth it as just a basic mod. But don't expect 35mph without some porting and other work. Also it is slightly loud, but it sounds like a little dirtbike.

Decent exhaust, broke along the frame mounting bracket multiple times, not a problem if you have a welder
