This looks awesome, but it is too tiny for anything above 110cc. Sounds awful too.

I disliked the dent but that was shipping I assume and not a big deal. I took that db killer out so idk what it sounds like with it , without it sounds great quiet enough but still sounds like a Harley. I made an exhaust for my sportster 1200 and thought it would’ve been too much restriction, turned out to be ok. Fit and finish was better than I expected, for the price it was a good buy.

I spend a lot of time restoring and building vintage Honda motorcycles. Typically, people either want to go ALL-IN with premium parts OR they want to pursue a quality, budget build. I'm pleasantly surprised with how this exhaust muffler worked on a recent CB/CJ 360 project. I mounted this exhaust onto OEM CJ360 headers and the result is pleasing to me. As with other budget friendly, universal parts... You need to be willing to spend time mocking up and fabricating a solution. If you have a bolt-on expectation, this probably isn't the exhaust for you. Very pleased overall and would purchase from them again for a budget friendly build.

The pipe is well made sounds okay the stainless is very cheap and does stain very easily I wound up painting it it looks better flat black anyway in the way I'm using it. If you do choose to paint it definitely scuff it up a lot and buy a high quality paint I chose vht and it started flaking so I would not recommend vht unless you're ready to bake it in an oven which is recommended and I did not do and it is flaking off.
