Sounds great definitely recommend
I didn't really know how this would sound for it being so cheap but I put it on my 425 and it sounds amazing

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.

Best Sound Kawasaki Ninja 500
Absolutely love this slip on exhaust over the Leo Vance and yoshimura for both price and sound. All the other slip on for the 2025 ninja 500 are too loud in my opinion. I leave early for work and do not want my neighbors to hate me so wanted something deep and not obnoxious and raspy like the full Yoshi system. This did it for me. I had to buy the mid pipe adapter separately on here for $27 to make it bolt on but it did. There are some small exhaust leaks around both joints of the mid pipe adapter but minor I’m going to leave it alone. Also no gaskets were used (or supplied) so I expected the leaks. Only found out by passing my fingers around the joints at idle and I felt little puffs of exhaust air at both connections. If I cared enough I could take it apart and use the original gasket if I could get it out and some type of sealant but I’m not sure if it’s worth all that. Highly recommend!

It’s great, just hard to get on
It sounds perfect to me, but was very hard to pu on my Honda 2018 420 rancher. This exhaust is stainless steel, while my pipe that was on my bike was steel. THESE CANNOT BE WELDED TOGETHER. We had to use clamps and used JB welding rap for sealing off the connection for exhaust to muffler. We also were unable to use springs that were included the brackets to put on pipe are also stainless steel.

Great Sounding Muffler
FIRST, this is not a bolt on part. You will have to weld the adapter to your pipe after cutting off your old muffler. The muffler looks and sounds great though. It doesn’t come with a baffle so it’s pretty loud. It was way louder than it sounds on video but it’s a lot better than the straight pipe I had. Overall satisfied with it and would reccomend!

Not too bad.
Build quality is great,but really needs a DB killer option. Pretty much just a straight pipe.

Videos don’t do the sound justice
I have a ‘19 Cbr300r and I gotta say, I tried another exhaust that was short but it was way too loud which you’d think is good but it was too poppy/slappy and quite cheap sounding. It also made the bike run rich. You could smell it. THIS one, on the other hand, because it’s longer, doesn’t sound like a tin can. At lower rpms, it has a deep sound, making people question if my bike is actually a 300 lol it also feels good to know people can hear me coming because that’s a safety issue in the fast-paced city if no one hears a quiet bike. On the freeway, it can sound a bit like the bike is screaming but a 300 is always pushing at those speeds. You NEED a midpipe. There is no way around it- even the shorter exhausts just won’t fit. I’m extremely happy and wanted to make sure I came back to share this because it’s perfect ! My bike did not need adjusting of any kind. It does not run rich compared to other exhausts I tried. My guess is you need an exhaust similar to the size of the stock to minimize any changes in power and such. I’d upload a video but they don’t do the sound any justice- it doesn’t sound the same on video as it does in person! 10/10

Good purchase for my ATV
Installed on 2022 CFMoto CForce 800xc. I’m very happy so far. It’s not quiet but it’s not too obnoxious either. It has a deeper tone than the “fiberglass” options that are available here and seems sturdier too.

Not overly loud just perfect
Better than I was expecting for the price

Bien por el precio, buen sonido
No tiene DB-Killer y tienes que adaptar uno en caso de que quieras ponerlo. El vendedor me ayudó a seleccionar y resolver el tema del DB-Killer y aunque la construcción presenta fugas, no es nada que afecte el performance o el sonido de manera importante. Es bastante más ligero que el OEM. Recuerda usar pasta para montaje.
