Q: Do I need a jet kit with a slip-on? A: In order to get the most from Erion Racing slip-on or bolt-on system, we recommend a jet kit. Q: Do I need a jet kit with a full system? A: Yes, we recommend a jet kit/power commander with all full systems. In order to obtain optimum performance, the air/fuel mixture must be changed throughout the RPM range because the Erion Racing system is less restrictive than the stock system. Q: What is the difference between the titanium system and the aluminum system? A: All systems are constructed of the same aerospace-grade stainless steel, with the canisters wrapped in either black powder-coated aluminum, or brushed titanium. Titanium is more durable, and stronger than aluminum. However, as a more exotic material, it is more expensive. Q: Why use a slip-on or bolt-on rather than a complete system? A: A slip-on or bolt-on gives a better sound, and more power than stock, but not as much of a power increase as a full system provides. Q: How does the exhaust system mount? A: Most systems mount in the stock location using stock hardware. If special hardware or mounting material is needed, Erion Racing can provide it. We sell optional aluminum brackets to replace the rear passenger foot peg/ exhaust mount for most sportbike models. Q: Do you recommend a bolt-on ignition advance rotor? A: No, a bolt-on advance rotor advances timing through the complete RPM range, which can cause a decrease in power at some RPM levels. Q: What type of air filter should I run? A: Erion Racing uses the stock Honda air filters because they produce the most consistent horsepower of all filters we have tested. Ask a Question site map | site terms of use | release of liability
