Buying Guide
What to consider when choosing shorty slash-cut mufflers:
- Bike compatibility: Confirm header pipe diameter (1-1/2″ vs 1-3/4″), mounting options (left/right), and whether a reducer is included.
- Length and fit: Shorter (12″) vs longer (16″) bodies affect ground clearance and exhaust tone. Measure space in your frame to avoid interference with foot pegs or suspension.
- Sound and tone: Single-chamber and straight-through baffles produce deeper, louder tones. Consider whether you prefer a subtle aggressive sound or a bold, loud exhaust.
- Finish and durability: Flat black coatings resist heat wear and look best on monochrome builds; chrome or polished finishes offer a brighter aesthetic but may require more maintenance.
- Installation effort: Look for included mounting hardware, baffles, and reducer shims. DIY-install friendly options usually save time and keep costs down.
