PACEWALKER Motorcycle Exhaust Muffler 1.5-2" Inlet, 38,51mm, Matt Black | Removable DB Killer, For Street/Sport Motorcycles and Scooters Exhaust Pipes, Dirt Bike ATV Street Bike

Sounds great, a few options with the db killer , the threading is cautious , don't overtightened. You can also take the inside of the db killer off for a medium between full noise reduction and full flow exhaust. Great sound, performance. Would def recommend

Let me start by saying the only thing less cool than a scooter is a loud scooter. However this was the last piece to my build. I built the engine of fiddle 2 scooter to 180cc (yes 63mm), big valve ported head, cam ect. I really wanted to keep the stock exhaust, I cut the rear most baffle out of it which was about as much as I could do with the stock muffler. I wanted to see if the stock exhaust was holding me back. I bought this because number one it was cheap but also it was black! It seems every aftermarket muffler on the market is some version of chrome and anodized looking colors. I had a front pip from an ice bear trike so I cut it up, welded the spring tabs on and used a gy6 swing arm to make a bracket. I’m pretty impressed. The quality is good. Something to remember is this is a straight through muffler with fiberglass packing. It’s loud, there’s no way around it. The silencer helps but it’s still loud.l way beyond the stock exhaust. I didn’t notice much of a performance bump. Certainly didn’t gain any top end. These little engines don’t need a straight through muffler with a 2” bore. However there’s not many options out there. It will stay on for now, I’m starting to get used to the little grow of the 180cc.

Good sounding exhaust. Looked good till the paint started chipping off after the first ride. My bike is tuned, so its not excessive heat. Maybe put a higher temp paint on it?

This product caused me extra headaches! I don’t have much experience with motorcycle modifications, so I chose this exhaust muffler based on its advertised functions and appearance. When I received it, I couldn’t install it on my bike right away. Later, after some time passed, I installed it myself and discovered that some necessary parts were missing. Because of those missing parts, the installation looked awkward, and the exhaust did not look good on my motorcycle. I have some regrets about this purchase. The product may work, but it should include all the required parts for proper installation and a better final appearance.

Very cheaply made. Obviously price made it suspiciously tempting. May be fine for a small scooter under 200cc or so. I installed On my Duke 390 and within 1-2 minutes the packing was already blowing out. So expect to have to repack if you buy one. Also, the removable “DB killer” insert bends and sticks out just from the pressure of the exhaust. The screw won’t stay tight because where it screws into is extremely thin like sheet metal and has no holding power. It’s very loud which is somewhat expected with a short silencer. But not this loud.

This is my initial review of this muffler after just installing it and taking the bike for a quick ride. I installed this onto an eBay midpipe that originally came with my knockoff SC Project race exhaust—which was just way too darn loud. I really wanted a Yoshimura R77, but they don't make them for the Honda CB300R anymore, making a good exhaust tough to find. I stumbled across this one on Amazon, and for around $35, and I figured based on many of the reviews, it was worth a shot. My initial impression? Not bad at all. For context, I had previously purchased two different types of decibel killers from Amazon to see if I could quiet down the SC Project exhaust. I ended up using one of them inside this new muffler, in addition to the DB killer it came with. If you check out the video linked here, you can hear how it sounds with both installed. I did briefly test the bike with only the included DB killer, but it was still a bit too loud for my taste. Adding the second DB killer to the 51mm inlet side (https://a.co/d/04Czj9nh) made all the difference, and I'm really glad I did. Overall, it sounds great—way better than stock, and a massive improvement over the SC Project knockoff, which was killing my ears. I have no idea how long a $35 exhaust will last, but for the price, I'm happy with it for now. Plus, I think it looks significantly better on the bike than the bulky stock exhaust. Hell, I may purchase another just to keep on hand for later since finding something that works, and you like, can be difficult. Update - 6/23/2026: So, I went with the matte black on based on someone commenting that the carbon fiber looking one peeling. Apparently, the peeling isn't only on the carbon fiber one. This muffler has only been on the bike for about 7 days, and maybe 100 miles of riding total. Update - 6/27/2026: I switched to the "titanium" version since it is all metal (no paint) to see how that will hold up (pics provided as well after riding with it for a few days.

Used on a 2016 polaris sportsmen 570 efi. Springs were a pain and had to bend them out some but still fit nice and tight. I also had to make a custom bracket to make work. Sounds amazing and gives just a little more take off speed plus a mean and low sound. Db killer makes a huge difference removing so if you dont like it loud do not remove. Just remove bolt and pry out the baffle to remove as this came with no directions.

This exhaust is great for daily riding, it's not too quiet, but it's also not pretentiously loud. The appearance is fine, fits with most styles, and installation is very easy since it just slips on. One thing to note, the DB killer screw is a touch loose, some high temp thread lock will help make sure it doesn't fall out.

Muy resistente llevo 24000km y ahí está como nuevo

Sin db killer suena bastante y con el puesto más agradable

De la grosse daube 1h de roulage la peinture c est barrer la chicane pareil et la laine de verre dedans ce barre a la moindre accélération

Is not 51mm so it is useless. Looks ok but you always get what you pay for

faz um barulho muito bom, suprendeu pela positiva
