The Best Exhausts for the Dyna Street Bob

Looking to find the best exhaust for the Dyna Street Bob, I set out on a journey, testing over a dozen different exhausts. My hands-on experience aimed to identify those with the best build quality, highest performance, most pleasing sound, and taking into account design and cost.

Through grease-streaked hands and the roar of engines, one exhaust really caught my attention: Bassani’s Road Rage II. This 2-into-1 style pipe was not just a piece of metal; it was a powerful beast. As I revved the engine, I could hear a fantastic soundtrack, louder and fuller sounding. The retro bobber-inspired styling just clicked, making it a standout in the crowd.

Having spent over a decade testing and reviewing motorcycle exhausts, accessories, and other parts, I’ve grown attuned to what really works on the road. My garage has become a haven for these mechanical marvels, each telling its own story of performance and design.

So if you’re in need of an informed opinion to help guide your buying decision for the Dyna Street Bob, you’ve come to the right place. Stick with me, and I’ll share more of my thoughts and insights on what makes an exhaust not just good but truly exceptional.


Overall Best

Bassani Road Rage II 2-Into-1 Dyna Street Bob Exhaust

The moment I fitted Bassani’s Road Rage exhaust onto the Dyna Street Bob, I knew I was in for a treat. This exhaust, with its loud and beefy note, premium construction, and power boost, had me hooked.

The classic 2-into-1 style spoke to the Dyna Street Bob’s character. Fashioned from premium stainless steel, I could feel its durability, and I knew it would withstand higher temperatures and pressure.

I had the option between classic chrome or a black satin finish. The chrome variant, with its contrasting black billet end cap, looked sleek, but my hands found a connection with the satin black, which perfectly matched the Dyna Street Bob’s blacked-out engine.

As I installed the exhaust, I appreciated the integrated heat shields, knowing they’d be a blessing on longer journeys. The design seemed to account for the Street Bob’s taller shocks, mounting higher and preventing scraping on large bumps, providing more room to lean the bike over.

When I fired up the engine, the boost in power was undeniable. The 2-into-1 style channeled a higher, more concentrated exhaust flow, and I could feel the added horsepower, making the bike feel faster and smoother. The torque gains seemed to propel me to 60 with a new eagerness.

But what really caught my heart was the sound. Oh, that exhaust note! Louder than stock, yet deeper and more crisp. It became my favorite exhaust note of any pipe I’d handled. And as I toyed with the removable baffles, the option for even more volume left me grinning.

This wasn’t just an exhaust; it was a symphony of engineering, and I knew I had found something special for the Dyna Street Bob.

Pros
  • Premium stainless steel
  • Comes in chrome and satin black
  • Integrated heat shields
  • A free-flowing exhaust design boosts power
  • Bike accelerates faster
  • Specifically designed for Dynas with taller shocks
  • No scraping on large bumps
  • Louder, beefier sound
  • Deeper exhaust note
  • Removable baffles can make it even louder
Cons
  • The design may not be to everyone’s liking

Worthy Consideration

Bassani Radial Sweepers Exhaust

Another Bassani exhaust caught my attention, and though it couldn’t match the power of the 2-into-1 pipe, the grunt it put out was impressive. And loud? This one was even louder than the last. In fact, I found myself wondering if it might be a bit too loud!

The Radial Sweepers seemed to be the polar opposite of the Road Rage, at least in design. Both shared the same high-grade 16-gauge double-wall steel, and both were equipped with full-coverage heat shields, but that’s where the similarities ended. This was a proper true dual compared to the Road Rage’s 2-into-1.

As I inspected the exhaust, the shorter design was evident, a feature that helped it produce as much power as it did. The look was decidedly more aggressive, with its backswept design and slash-cut ends.

When I mounted the shorter design, I felt the higher exhaust flow resulting in enhanced power and torque. In my hands-on tests, the throttle response was noticeably better. The bike felt alive with faster 0-60 times, and the engine just seemed peppier.

The sound quality? Much improved. Those shorter proportions worked magic. I was greeted with a louder, rowdier exhaust note, deeper and meatier. It had me grinning, though I knew it might be a bit too loud for some areas, so I decided to leave the removable baffles on.

The only drawback that stuck with me was the heat shields. They felt as useful as cardboard, doing little to shield the heat! The higher mounting prevented the pipes from scraping the road and allowed for further leaning, but it also positioned the mufflers closer to me as the rider.

Despite these nuances, the Radial Sweepers had their own charm, a raw, unapologetic presence that demanded attention. And I couldn’t help but admire their bold character.

Pros
  • 16-gauge double-wall steel
  • Backswept design
  • Mounts higher on Dynas with taller shocks
  • No scraping on bumps
  • Aggressive exhaust note
  • Loudest true-dual exhaust for Dyna Street Bob
  • Low-end torque is noticeably improved
  • The bike is faster to accelerate
  • Heat shields integrated into the design
Cons
  • Higher mounting makes heat shields less effective

Premium Choice

Cobra Speedster 909 Exhaust For Harley

Cobra’s Speedster 909 exhaust caught my eye as I prepared to upgrade my Dyna Street Bob. With a stealthy look and a loud, in-your-face exhaust note, it promised premium construction and enhanced performance.

As I unpacked the exhaust, I noticed Cobra’s sleek and understated design. Crafted from high-grade stainless steel for durability, it seemed more restrained than most I’d seen. The full-coverage heat shields were completely blacked-out, except for a chrome inner tip that added a subtle touch of flair.

But it wasn’t just about aesthetics; this Dyna Street Bob exhaust was all about performance. Cobra had integrated their patented ‘PowerPort’ technology, which promised to enhance power across the rev range. I was skeptical but excited to give it a try.

As soon as I hit the road, I was struck by the massive power gains. The bike’s overall torquier character was a thrilling experience, and the throttle felt smoother and more responsive. But what really got me was the top-end power. Seriously, I had to double-check because it felt like I was riding with a 2-into-1 instead of a true-dual exhaust out on the highway!

The sound was another delightful surprise. It wasn’t just louder; it was more pleasing to the ear. The acoustics were beefier, more imposing, and more aggressive. Being a true-dual exhaust, it had a crisp and powerful exhaust character that most 2-into-1 style pipes could only dream of.

Of course, not everything was smooth sailing. The installation process proved to be a hassle. I wrestled with the instructions, finding them less than intuitive, and trying to mate the exhaust to the Dyna was almost more trouble than it was worth. Frustrated, I ended up taking it to a professional, and I’d recommend you do the same.

Despite that hiccup, the Cobra’s Speedster 909 left a lasting impression on me. It was more than a piece of equipment; it was a personality, a statement, a breath of fresh life into my Dyna Street Bob. It had its flaws, but the thrill it offered more than made up for them.

Pros
  • Understated design
  • Better low-end torque
  • Integrated heat shields
  • Ideal for longer rides
  • Powerport technology
  • More power throughout the rev range
  • Smoother throttle response
  • Lightweight design
  • One of the loudest Dyna Street Bob exhausts
  • Deep, rumbly, exhaust character
  • Outperforms most 2-into-1 style exhausts
Cons
  • Not the easiest to install
