- Designed to give maximum horsepower without sacrificing low-end torque
- Anti-reversion design works to impede reverse flow through the system -- reverse flow can contaminate the incoming fuel/air mixture, which reduces performance and throttle response
- As reverse flow enters the collector, the diffuser deflects it through vents; the pyramidal trap and apertures impede the reverse flow, allowing time for the exhaust valve to close
- Flow director has equal area at each end, allowing exhaust gases to travel at a constant velocity over the entire length to improve exhaust scavenging
- For Heat Shields order H25-036
NOTE: There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (blueing) is the result of tuning characteristics, cam timing, carburetor jetting, overheating, etc. and is not caused by defective manufacturing. See lubrication products for products that will help prevent or remove blueing.
