Best 2 into 1 exhausts for Harley Davidson Sportster Motorcycles

Harley’s Sportster line of motorcycles has always been a fan favorite. We have been riding the Sportster for years and we feel that the performance and comfort these machines offer are top notch. 

That said, even great motorcycles can get a bit bland after riding them for so long. They deserve an equally excellent exhaust to spruce up the performance. Read on to find our picks for the best 2-into-1 exhausts for the Harley Davidson Sportster.

We can tell you from experience that while the Sportster is fun and enjoyable on its own, it requires that extra bit of ‘oomph’ from a quality pipe shine. Below, we’ve outlined the exhausts we had the best results with. Whether it’s an increase in power, improvement of sound, or just plain old customization of the bike, these exhausts have it all.

Bassani Road Rage III 2-into-1 Exhaust

Overall best

As the name suggests, this exhaust is not to be taken lightly. Aggressive styling and an even angrier exhaust note make your bike look the part of a ‘bad-ass cruiser’. High quality materials and production make this one of the easiest products to recommend, given it’s excellent design and durability. 

TIG welds make sure the construction of the exhaust is top notch and that it can take anything the engine throws its way. A higher mounting position means you get to lean your bike further before the exhaust comes into contact with the road.

The lightweight stainless steel muffler reduces your bike’s weight significantly, making the already nimble Sportster even easier to maneuver. But more than just impressive build quality, the Bassani also brings decent performance improvements to the table.

A free flowing architecture is how the Bassani manages to produce that epic soundtrack that we love. With every twitch of your right wrist, the exhaust pelts out a raw, thundering bellow. It is not for the faint of heart to handle this monster. 

And it’s not just the sound. Power gains are a legitimate benefit of the Bassani 2-into-1. Our dyno tests showed a decent 3 horsepower increase all throughout the rev range, with low end torque benefiting even more. Not too shabby when you consider the fact that the only modification to the bike was the exhaust!

Cobra El Diablo 2-Into-1 Exhaust

Best affordable option 

Cobra is an exhaust manufacturer that always seems to offer a high quality product at a mere fraction of the cost of their competitors. Following this tradition, Cobra’s El Diablo 2-into-1 exhaust, tuned and explicitly produced for Harleys, is a seriously competitive exhaust for not that much money.

The exhaust in question offers a host of performance benefits, looks terrific on your bike, and sounds unlike anything else on Earth…or in Hell, for that matter.

The ‘El Diablo’ looks good. Devilishly good, we think. With it’s one of a kind collector situated before the foot pegs, cone shaped muffler, and rear cylinder header pipe that goes forward instead of back to wrap around the ignition cover, it is a distinctive look that looks unlike any exhaust system we’ve seen for the Sportster. 

Even at idle, you will notice the motorcycle feeling much more rowdy and aggressive. At speed, this Cobra exhaust lets loose, producing other-worldly sounds that show its meaner side. All the while, the engine will feel more responsive, thanks to the decent power up you get with this exhaust. Our dyno registered between 4 and 5 more horsepower and a nice increase in torque as well. These numbers are nothing to scoff at, and you will be able to feel the difference in everyday riding.

Two Brothers Comp-S 2-Into-1

Worthy consideration

There aren’t many brands that enjoy the same level of consumer trust and widespread adoption as Two Brothers. They produce some impressive products that are the perfect way to spruce up your Sportster and their Comp-S 2-into-1 is no exception. 

Here, we race inspired exhaust that has some great benefits for the Sportster. Besides just looking like a high tech hunk o’ metal, the Comp-S performs like one too. 

A stainless steel build means less weight for you to lug around on the street and the highway. Industry leading quality control means your exhaust is perfect in every way and will not let you down when you need it most. TIG welds ensure a perfect fit and increased rigidity for your exhaust. A more efficient exhaust flow mechanism allows for better performance and, of course, that unmistakable exhaust note. 

The sound of the Two Brothers is just as race inspired as the performance. This exhaust pipe would fit right in at the race track with a meaty, slightly higher pitched sound that is simultaneously pleasing and foreboding. Installing this exhaust is like allowing the Sportster to let its hair down. It is like a complete makeover. 

Performance benefits as well. More horsepower and torque are present but in a nuanced, subtle way. It is not overwhelming when you crack the throttle but gives you the impression that this bike means business. We loved the Comp-S for its best-in-class performance and think you’ll do too.


  • Race inspired exhaust with awesome performance
  • Lightweight build reduces overall mass
  • Cool design with carbon fiber endcap 
  • Handling improved thanks to better power to weight ratio
  • Megaphone style muffler offers louder sound


  • Other options produce better results
