Great purchase!
Fit well on a 1997 Kawasaki Prairie 400 4x4. Looks great and sounds great! Easy install, it slipped right onto exhaust pipe and the mounting bracket fit perfect and bolted directly into existing mounting bolt hole. The original muffler rusted off and this was an affordable way to replace it. It is louder than original but is a good trade off for the added power because of ease of air flow.

Sounds great, on the right bike.
A glasspack is a glasspack. Perforated metal tube surrounded by absorbent packing in a can. The longer the can the quieter. So it's no surprise this $40 can sounds nearly identical as a mileage worn $200 can of close size that it's replacing. No db killer included, but that's fine for me as I was running the outgoing muffler sans its quieting insert. I find the sound volume just at the threshold of acceptable volume with my old bike's catless header. You have a more modern bike with a catalytic in the header, it'll be even quieter. Construction seems solid and the welds look decent. I did some slicing with a rotary tool and modified the inlet to match the clamp set-up used on the outgoing muffler. Reusing my old 2" clamp and just tossed this new can on the link pipe already installed. Cool: Whether this sounds "good" is 99% your bike's engine and firing order. Doesn't matter if you spend $40 on this, or hundreds on a Yoshi system. If you don't have the right engine, no exhaust system will make it sound amazing. Throw this $40 can on a 2009+R1-MT10, VFR750-800, or RSV4-Tuono it should sound glorious. 270 degree parallel twins, SV650, V2 Ducatis etc. this will probably sound awesome. Meh: Put it on any standard firing high revving inline-4 it'll be like Vanilla ice cream. Tasty, but nothing special. Yuck: Put this muffler on a VFR1200 or Kymco125 if you just gotta have that lawn care equipment sound. Narrow angle V-Twins with offset crank pins (some Shadows, Deauville 650) please don't. Your factory exhaust is so much better.

Sounds great but sticks out in my setup
Fitted this to aftermarket titanium pipes which are bolted to an MT-07. The long tube headers with the collector installed are murderously loud. I actually flinched when I started the bike. I decided not to run the bike until I got a muffler installed, which is where this muffler came in. It was a direct slip on without any hassle. The reducer adapter was already inserted so I took that out without a problem. I even managed to fit the springs over the attach points without any tools, though one side was a bit loose and didn't apply any spring tension. Inside the box there are 2 tabs that you can weld on in case you need 2 more attach points. Very thoughtful! The video speaks for itself. In my specific case, my collector spits out the at an angle and any aftermarket slip on muffler would end up pointing outwards. It will definitely scrape on the next lean. Luckily, for the price paid, I won't shed any tears if it gets scraped up. I MIGHT raise a brow when a new hole shows up and gets super loud. I got a 14dB reduction in sound by adding the muffler to the end of the straight pipe. Works for me.

Decent for $40 (k3 gsxr 1000)
4 star. Only got it to mock up with my new midpipe for when I put my yoshimura can on. Actually might keep it on sounds kinda good. Not any louder than the last carbon fiber muffler I had on. Is a little "raspy" more high pitched than I thought. Decently constructed. We will see how it goes with a few miles. It's on my k3 gsxr 1000 and has a yoshimura sticker (Doesn't come with muffler) which I think doesn't look TOO bad. For $40 you really can't go wrong.

Cant go wrong!
If you want a nice throaty sound for cheap, this is the way to go. Through this on my wife's Canam Outlander 400 and its perfect. I ended up putting a small baffle in just to tone it down a wee bit, but it still sounds great for the money. Highly recommend

Sounds great
Looks way better than the other 40$ mufflers. It's not as loud as I thought it would be and I'm glad.

Exhaust leakage
It’s decent sounding but as others have mentioned: the actual build quality on the body is poor, I can feel exhaust leaks where the rivets are between the stainless section and the body. Wouldn’t be that hard to weld if the fabricator spent a little more time. I’d just get something even cheaper if you you’re ok with lower quality.
