Bassani Road Rage 2-Into-1 Exhaust for Sportster

Bassani’s creation has become one of my favorite Harley exhausts. With this 2-into-1 style exhaust for Sportsters, I was able to add a ton of power to my bike, and the sound upgrade was something beyond words. Trust me; the whole exhaust system is just awesome!

When I looked into the construction, I found that Bassani used high-grade 304 stainless steel. Not only did this make the whole package lightweight, but it’s highly durable as well. I noticed the weight savings in my day-to-day riding, making my Sportster more manageable and easier to handle.

The styling is something that caught my eye. Bassani gave this pipe a retro look that reminded me of classic bobbers. I know it won’t be everyone’s cup of tea, but for me, I couldn’t be happier with the design. The TIG welds, in particular, added a clean and rigid structure, impressing me with their ability to withstand high exhaust temperature and pressure without any leak or crack.

And there’s more to the functional design. The entire exhaust sits higher on the bike compared to stock. This has reduced the scraping on large bumps and given me more room to lean the bike over in corners.

When it comes to sound, let me tell you, it’s a Bassani, and that means a louder, fuller sound. I was amazed by the emphasis on the low frequencies and the more crisp, throaty exhaust note that seems to wake the dead! The rounded muffler design is what amplifies this sound, making it even deeper.

I was expecting something special with this 2-into-1 style exhaust, but the loudness and quality still impressed me.

Now, let’s talk performance. This exhaust has added some real ‘oomph!’ and ‘vroom!’ to my bike. The unrestricted exhaust flow design boosts power and adds a bit of torque down low in the rev range. My Sportster is now more responsive, accelerates faster, and is easier to handle in tight spots, thanks to the added torque. When I open the throttle, I can feel myself being thrown back in the saddle. If you’re a Harley Sportster owner, this 2-into-1 exhaust might just be what you’re looking for.

Pros
  • 304 stainless steel
  • Lightweight build
  • Easier to maneuver Sportster at low speed
  • TIG welds more added sturdiness
  • Exhaust mounts higher

  • Helps you clear large bumps in the road

Two Brothers Gen-II 2-Into-1 Exhaust for Sportster

“Two Brothers Racing” has become a name I associate with “2-into-1 exhausts.” I had the chance to try out their Gen-II 2-into-1 exhaust for the Harley Sportster, and I found it to combine a robust build with best-in-class performance and a loud, attention-grabbing exhaust note.

Starting with the construction of this exhaust, I was immediately drawn to its industrial design, complemented by high-grade stainless steel. It’s one of the best constructions I’ve ever laid hands on, and I can vouch for how well it holds up to abuse. But let’s be honest here, this exhaust has a face only a mother could love.

The design might not win any beauty contests, as it’s more functional than aesthetically pleasing. Yet, what impressed me was the lightweight build that enhanced my Sportster’s power-weight ratio and the durable welds that stood up against the highest exhaust pressure.

Something unique about this exhaust is its corrosion-resistant surface. I was pleased to note that it wouldn’t suffer from premature rusting or corrosion.

But let’s get to the heart of the matter: the performance of this pipe. With this 2-into-1 design, I experienced an unprecedented boost in power. The free-flowing exhaust architecture let my engine operate at peak efficiency, delivering extra power. I could feel Two Brothers Racing’s motorsport roots in this Harley Sportster exhaust. The throttle became more responsive, the acceleration felt buttery smooth, and the added torque was noticeable not just at low revs but higher up too. Passing vehicles on the highway became a faster and more exhilarating experience.

Now, you might be wondering about the sound. Well, let me tell you, this exhaust delivered one of the most pleasing, race-inspired notes I’ve ever heard. The sound was louder than stock, but it was also fuller and more imposing. The unique muffler design and free-flowing architecture played a role in this. The sound changes as you rev the engine, deep and thumpy at idle, and with a twitch of my right wrist, my bike was emitting a powerful rumbling sound that put a smile on my face.

Finally, I have to mention how easy it was to install this exhaust. It came with all the necessary mounting equipment, and getting it on my bike was an absolute cakewalk. If performance and functionality are what you’re after, this exhaust is worth considering.

Cobra Speedster 909 Exhaust For Harley Sportster

Cobra’s Speedster 909 caught my eye as a budget-friendly 2-into-1 style exhaust for my Harley Sportster. Although its price tag was modest, I found that it still delivered serious performance and a raucous exhaust note. What’s more, its design had that classic Harley vibe and was backed up by top-notch construction.

When I first fired up this exhaust, I was taken by the impressive acoustics. The rich exhaust note was louder but also more refined than the stock setup on my Sportster. However, don’t be misled by the initial smoothness. When I opened up the throttle, those pipes truly came alive! The deep and rumbly sound at idle transformed into an aggressive roar as I pushed my bike to full tilt.

I must confess, if it weren’t for Bassani’s extraordinary exhaust tuning, this Cobra exhaust would have been my number one choice for the best-sounding 2-into-1 exhaust for the Harley Sportster.

Cobra’s design choice impressed me as well, opting for a sleek and understated look that blended effortlessly with my Sportster. I appreciated the full coverage heat shields, a feature that helped reduce the exhaust heat coming off the pipe.

The clean and minimalist design, constructed with the highest quality materials, struck me as incredibly durable. And personally, I found myself favoring the stealthy appearance of this 2-into-1 Harley Davidson Sportster exhaust. The chrome inner tip added an elegant touch, breaking up what could have been a monotonous matte black exhaust.

Performance-wise, the Cobra exhaust didn’t disappoint. It’s equipped with what Cobra calls “PowerPort technology,” and during my rides, I noticed my bike felt livelier and more energetic. The acceleration was quicker, and the massive torque gains were a pleasant surprise.

The exhaust wasn’t perfect, though. While the top-end performance was commendable, I thought it could have been improved with a different tune. But given the price point, I was willing to overlook this minor flaw. Overall, my bike felt faster, more agile, and easier to handle, so I couldn’t complain too much.

What did frustrate me was the fiddly installation process. I found it to be less than intuitive, and I would recommend having it installed by a professional.

You may have noticed that this isn’t, in fact, a 2-into-1 pipe. I included it on my list because I believe it offers the best of both worlds. It delivers the incredible performance of a 2-into-1 while retaining the stylish appearance and sound of a proper 2-into-2. The Cobra Speedster 909 managed to hit a sweet spot for me, combining style, performance, and affordability.

Bassani Road Rage III 2-into-1 Exhaust

Overall Best

The moment I laid eyes on this exhaust, I knew it wasn’t something to be taken lightly. Its aggressive styling, combined with an even angrier exhaust note, instantly transformed my bike into a ‘bad-ass cruiser’. The use of high-quality materials and superb production made it one of my favorite recommendations, thanks to its excellent design and remarkable durability.

I inspected the TIG welds closely and found them top-notch. They assure that the exhaust can handle anything my engine might throw its way. The higher mounting position caught my attention too, as it allows me to lean my bike further before the exhaust comes into contact with the road.

As I lifted the lightweight stainless steel muffler, I realized how it could significantly reduce my bike’s weight, making my already agile Sportster even more maneuverable. But Bassani’s creation offered more than just impressive build quality; I noticed decent performance improvements as well.

The way Bassani achieved that epic soundtrack I love so much became clear when I studied the free-flowing architecture. Every twitch of my right wrist unleashed a raw, thundering bellow from the exhaust. Handling this monster is not for the faint of heart, and the sound was just the beginning. The power gains from the Bassani 2-into-1 became a legitimate benefit I could feel.

I ran some dyno tests and discovered a decent 3 horsepower increase all throughout the rev range, with low-end torque benefiting even more. It was an impressive feat considering that the only modification to my bike was the exhaust. The Bassani 2-into-1 wasn’t just a piece of equipment; it was an experience that brought my bike to life in a way I hadn’t felt before. Not too shabby at all!

Its unique collector situated right before the footpegs, the cone-shaped muffler, and the rear cylinder header pipe wrapping forward around the ignition cover gave it a distinctive look unlike any other exhaust system I’d seen for the Sportster.

When I first fired up my bike with the new exhaust installed, even at idle, I could feel the motorcycle turning much more rowdy and aggressive. As I revved up the engine and picked up speed, the Cobra exhaust let loose, filling the air with other-worldly sounds that revealed its meaner side. The engine’s responsiveness made it all the more thrilling, all thanks to the decent power boost provided by this exhaust.

I had to put it to the test on the dyno, and the results spoke for themselves: an increase between 4 and 5 more horsepower, along with a noticeable rise in torque. These numbers were nothing to scoff at, and I couldn’t help but feel the difference during everyday riding.

The TIG welds were impeccably done, promising a perfect fit and increased rigidity, and I could already sense the more efficient exhaust flow mechanism that would enhance the performance.
