Hello guys and girls, Would like to hear your opinions and advice, on whether the UMA Racing Backpressure Exhaust is suitable for a bike with the following specs: 1. 63mm CMS Racing Block with FJN Piston set 2. SCK Racing Camshaft 3. SCK Racing Valve springs. 4. BRT 19/22 Head set Port and Polished 5. API Tech Standalone ECM 6. Mikuni 32mm Throttle Body 7. Uma Racing 160cc Injector 8. CJ Ipoh VMB Standard-Cut Exhaust without stopper The problem is with my current exhaust, it is too loud My neighbours are angry, my wife is angry, even other motorist on the highway are angry at me. So I would like to have another set of performance exhaust without too much lose of power, and most important, not too noisy! Cheers!
