All Gild series slip-on/bolt-on exhausts have undergone extensive R&D
Dyno tested and tuned to work perfectly with your stock fuel curve/mapping
Feature stainless steel mid-pipes and show-quality polished stainless steel muffler shells, end caps and tips
Huge 2.5” diameter outlet tips have an aggressive 55° slash-cut that screams MotoGP and/or Stunter styling
Muffler shells are extremely lightweight and robotically welded for a seamless fit
6061 T-6 aluminum billet end caps are CNC-machined from solid material to exacting tolerances
Components are so precisely machined and assembled, that they require only four stainless steel button head screws on each end to secure them
Exit caps are stylishly milled with the Boz Brothers B logo and tribal etching
All systems available with street core or racing core, and are packed exclusively with long-lasting Silent Sport Premium from Germany
Street cores feature 18” L muffler shells and 2” high-percentage perforated cores to assure a quieter exhaust tone; most average 82-84 dB at idle, 93-95 dB at 5000 rpm (tested statically at 20”, 45°); undertail models have shorter mufflers so sound levels will be slightly higher
Racing cores feature 15” L muffler shells and 2.5” low-percentage perforated cores for maximum flow and aggressive exhaust tone; most average 85-88 dB at idle; 97-100 dB at 5000 rpm (tested statically at 20", 45°); undertail models have shorter mufflers so sound levels will be slightly higher
NOTE: It is recommended that new exhaust gaskets and a proper jet kit be installed when changing an exhaust system on a carbureted motorcycle. It is recommended that new exhaust gaskets and a Power Commander be installed when changing an exhaust system on a fuel-injected motorcycle. See the Engine section for exhaust gaskets and the Fuel Systems section for jet kits and Power Commanders.
NOTE: There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (blueing) is caused by tuning characteristics, i.e. cam timing, carburetor jetting, overheating, etc., and is not caused by defective manufacturing. See the Lubes section for products that will help prevent or remove blueing.
