Universal Slip on Modified Exhaust Mufflers with Silencers Compatible with Motorcycle Grom ATV Dirt Bike Street Bike Scooter Pipe Diameter 38mm-51mm Exhaust,Black

If you are looking for a quiet muffler, this isn't it.This muffler is loud(!) and gives a Ninja 400 an aggressive snarl that other slip-ons I've bought can't match. It probably cuts the volume of going without any muffler by 33% and transforms the sound into a throaty "blat". It's close to obnoxious at full throttle but has a just muffled drum roll at idle. Downshifting and trailing throttle causes the exhaust to warble like it is wants to pop and backfire but doesn't. It's hard to describe properly.The chrome/blue finish was perfect when installed and it's still flawless after 6 months and a few thousand miles. The installation was easier than some due to the included installation springs being less stiff than those that come with other aftermarket mufflers.This is a great value and will give your bike a new voice that can't be ignored.

I have a scooter with a 150cc GY6 engine and recently upgraded to a head with larger valves and ports. The header I built to match this uses a slip-on interface so I could easily change the muffler if it got damaged, destroyed, or annoying. Given this, I didn't want anything either too large or too expensive but still looked and sounded decent. This checks all of those boxes handily.I knew it wasn't real carbon fiber and was kinda worried it would look cheap. This doesn't until your are bending over to look at it in full sun or with a flashlight.. There is a pretty obvious "seam", it's a solid tube, where the transfer pattern doesn't line up. But, thankfully, this is facing the scooter when installed (on the right side in my case). I would call the welds neat and tidy, which is more than acceptable in this price range. Even the spring loop welds are nice, with 2 neat tacks under each side and another from the wire tips to the tube. The baffle fits great, with no rattles after it's mounted. The baffle also has a pretty drastic impact on the sound. It has a deep tone either way, but without it is much louder and there is some of that angry rasp that lots of sport bikes have. The only nit I can pick is that the bead roll on the tip is a bit rough, like it was done too fast or at the wrong temperature. But, again, it's only really noticeable when you get right up on it.If it were more than 50 bux I'd most likely give it 4 stars. But at anything under 50 I'd say it's a solid value and worthy of 5. If I did it all again, I'd most likely save a few more bux and go with one of the blue options.Stay safe, peeps.

I bought this exhaust for my son’s bike, and it’s been a great upgrade. The sound is bold but not too loud, and the included silencer gives flexibility. Installation was quick, and it fit perfectly on his bike. It looks sleek with the black finish and has held up well so far. Overall, it’s a great value for the price, and my son loves it!

It's not a muffler; it's a sound modifier. The quality seems fair, I had a hell of a time trying to fit the mid pipe onto the exhaust on my cfmoto 450nk, the mid pipe wouldn't fit on the exhaust, almost there, but wouldn't go in, I had to heat, tried many hundred time in different ways, used rubber mallet etc. and finally after 3 hours, the sound is good with the baffle is good, the baffle does not fit firm, but doesn't rattle as yet.I would give it 4 stars, not sure if it was the mid pipe or the exhaust, had a hard time fitting both onto my bike!

Installed on Grom Clone. Sounds amazing on the 190cc. I did not install the baffle so it is loud and deep but I lIke it.

Looks good and sounds good have it on a 2000 sv650 motercycle

Sounds good with the baffle installed on my z1000 I enjoy the tone quite alot, its not obnoxiously loud and has a deep throaty tone. Typical issues with fitment as you will get with any universal muffler but being a mechanic, only took me about an hour and some welding/ fab work to fit the pipe and make a mount to hold the muffler

Held up decent, baffle fell out in puddle
