Direct answer: The our universal exhaust muffler is a 365 mm slip-on exhaust with a removable DB killer, sold in black, silver and burnt-blue finishes. It fits 38–51 mm pipes, bolts on without welding, and is the best-selling SKU in an exhaust range that has moved thousands of units through our own retail storefronts in two years. It is not a high-margin part. It is a high-turnover part, and that is the point.

Why an exhaust range moves thousands of units

We publish our own retail data so a buyer can judge a part before committing to a container. The exhaust range as a whole has sold thousands of units in two years on our own storefronts. That number includes the our universal exhaust muffler and the rest of the slip-on and full-system range we carry.

Exhausts are different from lighting or switches in one respect: the buyer is usually replacing something that is already broken, bent or rusted, and the decision is driven by fitment and sound rather than brand. That makes the market more price-sensitive and less loyal to any single listing. A part that sells thousands of units across a range is a signal that the range covers the right bikes at the right price, not that one SKU is dominating.

One thing to be clear about: [sales data] is our direct-to-consumer volume only. It does not include wholesale orders, distributor shipments or OEM runs. Those are larger and we cannot document them the same way, so they stay out of the count.

What an aftermarket exhaust actually changes

The factory pipe on a commuter bike is designed to meet noise and emissions rules for the market it was sold in. That is a reasonable starting point, but it is also a compromise: the same baffle that keeps the noise down restricts the flow, and the same heat shield that protects the passenger footpeg adds weight.

An aftermarket slip-on like the our universal exhaust muffler changes two things. It changes the sound by removing or replacing the DB killer inside the can, which is why the same pipe is sold with and without it. And it changes the look, which is why the same shape is offered in black, silver and burnt-blue titanium.

What it does not change is the header. The our universal exhaust muffler is a slip-on, which means it clamps to the existing pipe. It does not replace the down-pipe or the collector, and it does not require welding. That is the practical advantage for a dealer: the fitment is a bolt-on job, the customer keeps the original header, and the installation time is twenty minutes rather than an afternoon.

our universal exhaust muffler Black: the volume seller in this range

The black our universal exhaust muffler has moved more than thousands of units through our own storefronts. That is the highest single-SKU volume in the exhaust range, and it is not because the pipe is unique. It is because the pipe is the safest buy for a rider who wants a different look and a different sound without changing the mounting, the clearance or the emission setup.

The can is 365 mm long and 51 mm slip-on. The 51 mm connection covers most 38–51 mm stock pipes, which is the range on commuter bikes, small-displacement standards and most scooters. The clamp is included, and the springs are included. The DB killer is removable, so the same pipe can be sold as a quiet slip-on or a louder free-flow depending on which end cap is fitted at the factory.

The finish is baked paint, not anodized. That is why the black and silver versions are cheaper than the burnt-blue titanium: the titanium version requires an extra pass in the finishing line, and that cost shows in the price. For a dealer, the black version is the safer stock because it matches every frame colour and does not show surface rust the way a bare stainless or titanium can after a wet winter.

What is in the box

One pipe, one clamp, one set of springs, one universal connector. That is the complete kit for a slip-on installation on any bike with a 38–51 mm stock pipe.

The connector is the part most installers miss when they are comparing listings. A 51 mm slip-on only fits a 51 mm pipe. Most commuter bikes have smaller down-pipes, so the connector bridges the gap between the stock outlet and the slip-on inlet. Without it the job needs a reducer or a weld, and that is workshop labour rather than a swap.

The DB killer sits inside the outlet. It is held by a small circlip, and removing it is a two-minute job with a pair of needle-nose pliers. The same pipe therefore covers two markets: the rider who wants a legal, quiet slip-on keeps it in, and the rider who wants a deeper note takes it out.

Fitment and the bikes it does not cover

The our universal exhaust muffler is a universal slip-on for 38–51 mm pipes. That covers most Honda, Yamaha, Suzuki, Kawasaki and Chinese single-cylinder commuters, and it covers most scooters with an under-seat or side-mounted exhaust. It does not cover a bike with a 60 mm or larger stock pipe, which is where many current twin-cylinder standards and adventure bikes sit.

The burnt-blue version is titanium with a heat-coloured finish. It looks different from new, and it looks different after a long ride, because the colour changes with temperature. That is the selling point, and it is also the complication: a buyer who does not know what the finish will look like after three months of commuting should be shown a photo of a used one, not a studio shot on a stand.

The DB killer question

The DB killer is a metal plug with holes drilled in it. It sits inside the outlet of the can and breaks up the low-frequency pulse that makes a straight pipe sound like a drag bike. Remove it and the note opens up. Leave it in and the pipe stays within most track and noise limits.

It is a consumable. The can gets hot, the metal expands and contracts, and the packing inside the DB killer compresses over time. A rider who removes it and rides hard will notice the sound change within a few hundred kilometres as the packing settles. That is normal, and it is not a warranty claim.

For a dealer, the practical question is whether to stock the pipe with the DB killer fitted or loose. The answer depends on the market. In Europe, most buyers want it fitted and will remove it themselves. In Southeast Asia and South America, many buyers want it removed and will complain if the note is too quiet. The same SKU, two different expectations.

What 1,500 retail sales tell a buyer

thousands of units of the black our universal exhaust muffler is roughly six hundred a year on one SKU. That is steady, not viral. It tells you the pipe fits a large number of bikes, the price is right for the market, and the return rate is low enough that the listing does not get buried by complaints.

The sales split mirrors the exhaust range overall: Ozon and eBay carry the bulk of the volume, which means Russia and Western Europe are the strongest markets. The remaining sales are spread across our other storefronts in North America and Southeast Asia. That distribution is useful if you are deciding whether to stock the black version or the burnt-blue titanium: the black version is the volume play, and the titanium is the differentiation play.

One thing to be clear about before you read anything into the number: 1,500 is our direct-to-consumer volume only. It does not include wholesale orders, distributor shipments or OEM runs. Those are larger and we cannot document them the same way, so they stay out of the count.

What it costs you to move

Price is not listed here because it depends on the quantity, the destination and whether the order is mixed with other parts. Send the part numbers and your target quantity through the contact form and we will quote the whole carton. The margin is thin, which is why this is a stock item rather than a hero product.

The pipe is 365 mm long and the can is roughly 60 mm in diameter. A single piece in its retail box is light and compact: it sits on a shelf rather than a pallet, and it can be added to a lighting or body order without changing the freight calculation. That is the real advantage for a dealer. It is not the margin on one line; it is the fact that the customer who came for a headlight or a switch will also buy the exhaust because it is already in the cart.

Custom branding

Custom logo, custom packaging and graphic customisation are available. Logo and packaging start at 10,000 pieces; graphic customisation at 1,000 pieces. Those are tooling conversations rather than first-order conversations. Send the artwork and target quantity through the contact form and we will quote the setup and the unit cost.

Before you commit to a carton

Measure the stock pipe. 38–51 mm is the range, but the most common outlet is 51 mm. If the bike has a 60 mm or larger pipe, this exhaust will not fit without a reducer, and a reducer is not included.

Decide on the DB killer. If your market wants the pipe quiet out of the box, stock it with the DB killer fitted and include a spanner in the kit. If your market wants the deep note, stock it loose and print a one-line fitment card explaining how to remove it.

Check the finish against the catalogue photo. The burnt-blue titanium is the one that shifts colour with temperature. The black and silver are stable. Do not promise a customer that the titanium will look like the studio shot after a month of commuting unless you show them a used example.

Plan the termination. The slip-on needs a clean cut on the stock pipe. If the customer's original pipe is rusted or dented at the joint, the clamp will not seal and the leak will be louder than the note they paid for.

Questions dealers ask us

Will it fit a specific bike? If the stock pipe is 38–51 mm, yes. If it is larger, no. Send the make, model and year through the contact form and we will confirm before you order.

Is it legal for the road? The pipe with the DB killer fitted is within most noise limits, but limits vary by market and by test procedure. We do not certify it for any specific jurisdiction. Check your local rules before fitting it.

Can I have my own logo on the pipe? Yes. Logo, packaging and artwork. The minimums are 10,000 pieces for logo and packaging, 1,000 pieces for graphic customisation.

What is the minimum, and how fast? 10 pieces on this listing, and in-stock orders leave our warehouse in one to three business days. Mixed cartons with lighting, body and exhaust are fine, which is usually how this part gets ordered.
