I’ve put together this guide detailing the best 2-into-1 exhausts for Harley Davidson motorcycles, drawn from my own experience. Right now, I’m riding a softail, but I’ve been on various Harley models over the years. My recommendations here are not just words; they’re based on real comparisons and personal hands-on riding experiences with the majority of 2-into-1 exhausts out there.

The Comp-S is something special in its build. Out of everything I compared, it stands out for excellent weight reductions. And the torque! Believe me, it’ll make you fly off the mark. Don’t even get me started on that deep, loud purr. It’s music to any rider’s ears.

Two Brothers Comp-S 2-Into-1 Exhaust For Harley Davidson


When I installed the Two Brothers Comp-S on my bike, the first things that hit me were the explosive torque, that unmistakable screaming sound, and the sheer lightness of this exhaust. It was as if I had given my bike a whole new life, all without compromising on the build quality or the sleek aesthetics. Now, I do have to admit, it did cost me a pretty penny, and I noticed that the performance gains did lessen a bit in the higher ranges, but these were minor issues for me.

The Comp S 2-into-1 design is something to admire, with its sleek and compact appearance. When I ran my hands over those narrow pipes, I could feel how they’d been designed to shed even more weight, improving not just the torque but the overall performance of my ride. I managed to cut the weight of my stock exhaust in half with this beauty. Combining stainless steel and carbon fiber, the weight reduction was superb, and the power differences between this and the stock were immediately noticeable.

I’ve got to talk about the look and sound, though. The contrast between the piping and the muffler gives it a unique design that’s visually appealing. But what’s even more thrilling is the sound. I wouldn’t be exaggerating if I said this exhaust is extremely loud. When it’s idling, it’s quite peaceful, but the moment I play with that throttle, it roars to life. It’s a raw, heavy noise, but it’s not obnoxious. Even after a long ride, I still find myself loving that sound.

It’s not just an exhaust; it’s an experience, and I wouldn’t trade it for anything else.

Bassani Road Rage III 2-into-1 Exhaust


When I first laid eyes on the Bassani Road Rage III, I knew it was something special. This sweet-looking 2-into-1 exhaust not only stripped away a lot of weight but also massively amplified the torque on my Harley. The build quality was top-notch, and the longevity seemed promising, but what caught my attention was its lack of heat shields and somewhat lacking instructions.

Installing the Road Rage III was a fascinating experience. Leaning heavily on torque amplification, the exhaust’s short length and narrow diameter brought my Harley to life. I could feel those performance gains, further enhanced by the inner collector around the midsection of the piping. It not only funneled gases more effectively but also gave the exhaust a mighty roar that sent chills down my spine.

Switching out my standard stock exhaust, I could immediately sense huge weight improvements. The Road Rage’s compact stainless steel design not only took my Harley from a 2-into-2 to a 2-into-1 exhaust but also made it lighter and more powerful. The more narrow piping was a genius touch, and I could feel the power improvements across the board.

But it was the aesthetics that really sealed the deal for me. The matte black finish was a stunner, and the overall design with the contrasting muffler and pipes gave it a unique feel. That throaty roar was very similar to the Comp-S, and the similarity in design was no surprise.

However, I must mention a few drawbacks. The Road Rage didn’t include heat shields that covered the entire piping and muffler, leaving only partial coverage. Though not a major problem, it meant there would be more excess heat around my foot areas and other crucial components. And the instructions? Well, they weren’t the best. But thanks to the plethora of YouTube tutorials, I managed to get it installed without too much trouble.

Overall, the Bassani Road Rage III left me satisfied and impressed. The combination of design, performance, and that roaring sound made it an unforgettable addition to my Harley.

Cobra El Diablo 2-Into-1 Exhaust


When I came across the Cobra El Diablo 2-into-1, it immediately caught my eye. This beauty shared the same design as my other recommendations, but what made it stand out was the slightly more curvature. It gave the exhaust a sleeker look, not to mention similar power improvements around the lower power ranges, and all at a price more affordable than the Road Rage and Comp-S. But one thing that made me pause was that its build quality didn’t quite match up.

Having spent a considerable amount of time testing and comparing different 2-into-1 exhausts for Harley Davidson, I kept coming back to this specific design. Why? Because it consistently offered the most benefits. It ripped away excess weight with its compact design, narrow piping, and quality stainless steel construction. It was thinner yet managed to maintain impressive durability and longevity. But the real magic was in the shortness of both the diameter of the pipes and the length of the full system, ensuring maximum torque, something two-into-one exhausts are renowned for.

Cobra’s design choice to stick with a similar cone-shaped muffler struck a chord with me. It gave the exhaust a throaty roar, accompanied by a deep putter at idle. Although I found the sound pleasing, it lacked the profound deepness that I’ve experienced with more expensive alternatives.

In terms of overall quality, I must admit that the build felt less robust compared to premium brands like Bassani or Vance and Hines. Since I only reviewed this exhaust, it was hard for me to gauge what its longevity would be like. But delving into customer reviews, I found a reassuring consensus: owners of this exhaust for several years were very positive, and I couldn’t find any complaints concerning build quality.

In the end, the Cobra El Diablo 2-into-1 left a lasting impression on me. It’s a quality exhaust at an attractive price point, and while it might not be as weighty or robust as some other options, it more than holds its own in the field.

  • Cone megaphone muffler
  • Great customer reviews
  • Lightweight
  • Stainless steel
  • Compact design
  • Light weight
  • Lesser build quality compared to Road Rage and Comp-S
