Horsepower Inc. HPI-EXM8B-S Stainless Steel Full-Length Exhaust
Fits 2017–Newer M8 Touring Models
The Horsepower Inc. HPI-EXM8B-S is a full-length 2-into-1 stainless steel exhaust built for Harley-Davidson M8 Touring motorcycles. It is designed for riders who want strong performance gains, a deep exhaust sound, and reliable long-distance riding.
Because this system uses a true full-length design, it improves exhaust flow throughout the RPM range. As a result, riders experience better throttle response and stronger torque where touring bikes need it most. In addition, the sound is deep and aggressive without being harsh.
Each HPI exhaust is handmade in the USA using high-quality stainless steel. Therefore, durability and heat resistance are excellent, even during long rides or heavy use. At the same time, the clean TIG welds ensure a precise fit and long service life.
