Best aftermarket exhausts for your motorcycle

Almost every bike benefits from a new pipe

Fitting an aftermarket exhaust to a motorcycle

by Jim Blackstock |

It’s safe to say that the most popular aftermarket motorcycle accessory of all is an upgraded exhaust.

Whether you want to make your sportsbike or cruiser sound better, fancy giving your bike a bit of branded bling, want to cut weight or improve power or all of the above, an aftermarket replacement exhaust is the way to go.

But, with prices ranging from hundreds to thousands of pounds, a baffling choice of brands and an equally huge variety of types available — full systems or just silencer/can — it’s hard to know not only what’s out there but what you should go for.

Which is where we come in. This guide isn’t intended as a definitive explanation of what’s available for your specific bike — we simply haven’t the scope or space here to do that.

Instead it’s an overview to most of the different types and brands available, which should point you in the right direction to be able to make a decision about your machine.

So, with all that in mind, here’s our current guide to (some) of the best aftermarket exhausts available, in no particular order...

1. Two Brothers Comp-S Slip-On Can


A great example of a performance can for machines other than sportsbikes, in this case Honda's

Two Brothers Comp-S Slip-On Can

This one’s in matt- black stainless steel with a carbon-fibre end cap and, importantly, retains the bike’s stock 02 sensor. It’s also beautifully crafted and sounds great, although it’s not the cheapest.


One for cruiser fans

Respected American brand

Quality construction


Check it’s UK road legal

2. Akrapovic Full System, Yamaha YZF-R125


One of the biggest names in motorcycle exhausts, on one of the most popular 125s. Slovenia's

Akrapovic Full System u2013 Yamaha YZF-R125

A full system from cylinder to silencer, giving the biggest potential for performance enhancement, in 100% titanium for lightness, with an oval silencer in either carbon fibre or titanium. It sounds good, this one’s race only (due to noise, road versions are also available), enhances performance and is beautifully made which, at this price, perhaps it should be.


Best brand of all

Full system so most performance gain

Fabulous quality


This one race only – not road legal

3. Arrow Bolt-On Silencer, Honda CBR125R


If you can't afford or don't need the maximum performance gain a full system offers, a bolt-on

Arrow Bolt-On Silencer u2013 Honda CBR125R

With a titanium body and carbon fibre end cap it looks almost as good as a full system, is quicker and easier to fit, requires no re-mapping and yet still sounds and looks great – and all for a far more affordable price. With this Arrow (and many others) lots of different options, shapes and materials are available, but make sure you get the right one for your bike.


Reputable brand

Great looks and sound

More affordable and easy to fit


Hasn’t the extra performance of a full system

4. Gianelli Expansion Chamber, Vespa PX125


Although two-stroke powered two-wheelers are now few and far between due to tightening EU

Gianelli Expansion Chamber u2013 Vespa PX125

One of the leading brands is Italian scooter performance specialists Gianelli (which is also behind Arrow) with this pipe for the Vespa PX125/150 a typical example of its wares. It’s beautifully made, significantly raises performance and is of decent value, too.


Decent performance (and sound) hike

Reputable brand

Good value


Can require expert setting up

5. Yoshimura R-11 Slip-On Silencer, Suzuki GSX-S1000


Japanese brand Yoshimura can rightfully claim to be another of the world leaders in motorcycle

Yoshimura R-11 Slip-On Silencer u2013 Suzuki GSX-S1000

It comes in a variety of specs, either stainless steel, titanium or blued titanium, all with a carbon end cap and collector-box heat shield, has a detachable ‘DB killer’ baffle, looks and sounds great and is easy to fit.


Famous quality brand

Top quality

Variety of finishes


Premium price

6. GPR Slip-On Can With Catalyser, Yamaha MT-09


Here's another example of a decent, mid-range can, this time from the more affordable Italian

GPR Slip-On Can With Catalyser u2013 Yamaha MT-09

Nor is it as fancy-looking or in as exotic materials as some offerings, which may all add up to the question ‘Why bother?’ There is a double removable db-killer baffle, though, so at least you can make it sound good!


Street legal

Improved sound

Reasonable value


Requires stock exhaust to be cut

7. Scorpion RP-1GP Exhaust, Yamaha R1/R1M


Scorpion is probably the leading British aftermarket motorcycle exhaust brand and, like its larger

Scorpion RP-1GP Exhaust u2013 Yamaha R1/R1M

This is their high-end road/race can with a super-light carbon fibre construction a claimed 3bhp power improvement over stock (without need for remapping) and great looks and sound. It’s pretty good value, too.


Improved power/weight

British brand

Decent value


Less well-known than some

8. IXIL complete system, Yamaha MT-07


Another full system, this time from quality, but lesser known, French brand IXIL. The downpipes

IXIL complete system u2013 Yamaha MT-07

Performance is claimed to be slightly up, as is the sound; weight is usefully down, and long-term durability should be excellent – plus it’s even not that expensive! IXIL may not be as well-known as some in the UK but they’re worth checking out.


Good value

Improved performance all round

Lighter than standard


Lesser known than some

9. Bad Dog Oval Race Can, Triumph Tiger 955i


Another British exhaust/accessory brand, but this time one at the more budget end of the spectrum.

Bad Dog Oval Race Can u2013 Triumph Tiger 955i

It hasn’t the performance gains, options or quality of some more expensive alternatives but, at this price, is great value.


Good value

Stainless steel construction

Simple to fit


This one’s not road legal
