Will It Affect Back Pressure?

Talking About Exhausts And Very Often You Will Hear The Terms (Back Pressure) Or The (Right Back Pressure) Comes Up. Back Pressure Is Only Caused By Restriction And Has Little Or Nothing To Do With Performance Exhaust Design. Although Modern OE Super Bike Exhaust Systems Are Very Well Designed And Can Reduce Noise Levels To Conform To Emission Laws Without Offering Much Actual Back Pressure These Systems Are To Some Degree Still Restrictive. Performance Exhausts Work By (Pulse Tuning) Which Is The Use Of The Correct Pipe Lengths, Diameters And Correct Collector Configurations To Tune The Exhausts Pulses To Help To Fill And Scavenge The Cylinders. This Will Increase The Volumetric Efficiency, Which Will Intern Increase The Power And Torque. Therefore, Only Restrictive Exhausts Would Suffer Back Pressure. Pro-Race Exhausts Do Not Offer Any Restriction

Exhaust Valves?

Also Known As Set Valves, Exup Valves Etc. Some Pro-Race Exhausts Will Require This To Be Disconnected. The Primary Function Of This Valve Is Noise Control And Not To Boost Power (If It Was A Power Valve It Would Be On Every Race Bike But Does Appear On Any) Therefore Disconnecting The Valve Will Not Result In A Power Loss Or Affect The Running Of Your Motorcycle.
