Product Details

Firebrand Fiftytwo52 2-Into-1 Exhaust For Harley Dyna

Named after the RPM point at which an engines horsepower equals its torque, the FiftyTwo52 was engineered with one priority: performance. Featuring Firebrand’s proprietary Powercurve, True-Merge Collector, the FiftyTwo52 does not fail to deliver. Beginning with the 1 3/4" matched ratio head pipes, exhaust pulses are synchronized to allow for optimized scavenging of exhaust pressure. Flowing into the Powercurve, True-Merge Collector, the exhaust will maintain velocity and experience the smoothest transition possible. Moving into the muffler, a 2 1/2" free flowing, perforated core baffle provides the least interference as the exhaust escapes. What does all this mean? It means the FiftyTwo52 lives up to its namesake to achieve the best combination of horsepower and torque.

It doesn’t all end with performance. The 20 degree upswept muffler with Moto GP inspired end treatment attains a unique and aggressive style, while the dual layer baffle packing produces an incredibly deep race tone. Integrated heat shields and Firebrand’s hand crafted quality complete the package. Whether you choose show quality chrome or black ceramic finish, the FiftyTwo52 will not fail to impress.


  • Proprietary Powercurve, True-Merge Collector
  • Billet aluminum MotoGP inspired end cap
  • Race inspired, stainless core, high performance baffle
  • Unmatched combination of horsepower and torque

Firebrand did it again!
I bought the 4" Loose Cannon slip on for my 2014 FXDL and thought it sounded great with the head pipe catectomy. Fast forward, I was looking for a complete exhaust for my new 2016 FXDLS. Looked at all the brands and settled on black V&H staggered Shortshots. I don't know what Vance threw in the box, but the rear pipe wasn't even remotely close to fitting right. O2 bung was in a different zip code! I sent them back to Zilla and got back online to make another selection. This time I gave Firebrand a closer look. (should have been my first choice to begin with) The black Fiftytwo52 2 into 1 caught my eye. And Firebrand did me right with their slip on, so I gave them the chance to impress me again. Mission accomplished. The exhaust came securely shipped - no parts clinking around whatsoever. The instructions were easy to follow even without having diagrams. 2 into 1 is a little more tricky to get into place than 2 into 2, but it can be done by one guy with some simple tools. Masking tape is the key to keep parts from getting dinged and scratched. Once everything was bolted up, cleaned and the ECM flashed (Dynojet Powervision) it was time for the moment of truth. This exhaust sounds AWESOME!!! Throaty, deep tone at idle. Crack the throttle and it gets loud. Barking mad loud! It sounds like a Harley with a 110 should! I couldn't be happier with my purchase. I'd give it closer to a 4.25 rating. Durability - I'll have to get back to that one in a couple hundred miles. You will need new exhaust gaskets. (don't be a tightwad) Time to get out there and ride.
