Burns Stainless is excited to introduce the “No Holds Barred” (NhB) Exhaust for Harley-Davidson Milwaukee 8 ® baggers running big-inch competition engines.
“For years we have been working with many of the world’s finest big-twin tuners helping them win races, set records and make big power in dyno shootouts with our exhaust builds,” comments Vince Roman, Technical Director at Burns Stainless. “It became apparent that there were not any well-engineered stainless aftermarket systems available for these big engines, so we decided to offer a 2-into-1 system incorporating the famous Burns merge collector.”
The system is a 3-step equal-length primary exhaust with merge collector and reverse cone megaphone muffler. The merge collector and 3-step design provide a nice broad power band without sacrificing top-end power. The system will be available in two sizes, one for 107 – 117 cid builds and one for 117+ cid builds.
1-7/8” + 2” + 2-1/8” primaries with 3” muffler, for 117+ cid
Properly designed exhaust primary tube with floating flange to ensure smooth flow and maximum power
Primary length is adjustable to optimize torque and power and includes an adaptable header mount
100% Argon back-purged TIG welding for high strength and precision fitment
Systems are constructed from ASTM269 304 stainless steel tubing for best combination of weight savings and durability
Standard primary length is 33 inches - call for custom length
