Firebrand Smoothbore HeadersFirebrand Smoothbore Headers

– Firebrand Design, manufacturers of high quality, hand crafted motorcycle products, have released their new Smoothbore Headers for Milwaukee-8 equipped Harley-Davidson Touring and Tri-Glide models.  Engineered to fit under stock heatshields, the Smoothbore Header’s open collector design eliminates the congestion and allows the M-8 to breathe like it was born to. And by utilizing the stock  Harley heatshields and crossover pipe, Smoothbore Headers give all the benefits of a full header system, while retailing at hundreds less than the competition’s header systems. 

Designed to increase both airflow and decible volume, Smothbore Headers will add power and sound while reducing the heat attributed to stock headpipes.  Like all Firebrand products, Smothbore headers are manufactured in the USA and available online or through your local HardDrive supplied dealer.

I may be biased but I don’t think you can find a better looking exhaust for this Dyna Low Rider than our Chrome Upstarts.

Brandon over at Wolford V-Twin was kind enough to send us this dyno chart.  Below is everything they did for the comparison.

“We just finished the tune on our Dynojet 250I on a 2014 FLHTCU.  We ran the Firebrand Loose Cannons, Arlen Ness big sucker, TTS tuner, Header stock with the cat removed.  It performed really well.”



Thanks for the info Brandon, keep up the good work!



The Upstarts are Firebrand’s first full system 2-2 exhaust. Designed for riders wanting a shorter custom style look, without sacrificing power or sound quality, Upstarts feature 2.5” upward slash muffler bodies with Quadradical end treatments. Stainless steel, perforated core baffles deliver a high quality sound and improved performance normally associated with higher priced alternatives. Full coverage head pipe heat shields, 18mm O2 ports with 12mm inserts, and Firebrand’s high quality fit and finish round out the package. Upstarts are available for Softail, Dyna and Sportsters in both chrome and black ceramic finish.





Firebrand is excited to introduce their new Loose Cannon for Harley Street 500 and 750 models!  Unleash the deep roar the bike was meant to have, increase your performance, and add some aggressive styling…all at the same time, and all for under $250!  Check out our video on Youtube, and remember  Firebrand makes high quality, innovative products for motorcycles, not necessarily high quality innovative videos.
