This is a honest review..the muff sounds good. An does crackle and pop when u gas it.. only problem is the pipe rusted in 2 months..totally rusted. I’m not sure what to do now. I cleaned the rust with some pads and it just came back. Besides the rusting problem that’s probably from cheap steel.. it sounds good.. that’s why 3 stars.

UPDATE 5.5 MONTHS LATER!! Muffler broke at the weld in the header tube…….Looks amazing and fits pretty good ( 1 bolt on the muffler mount didn’t line up) I’m satisfied with the overall quality of the muffler kit but it’s a bit loud for a suburban community

It went on my 2023 kymco agility 50, it’s a must have modification. Very much worth it

I like the look and the sound is great at idle. Loud enough they will hear you coming for sure. As for the welds, they looked good to me. They gotta weld the pipe at a slight angle for a proper fit.So it’s been a couple months and the pipe broke at the weld. I kept getting the wrong bolts for the bracket and it never fit right. So now I gotta get a new pipe. Make sure to use the bracket!!
