Explaining, Designing And Building A Single Cylinder Four-Stroke Exhaust Pipe : SSR Part 10

I'll explain how four-stroke exhaust tuning works and build my own single cylinder four-stroke exhaust system in this video. The entire process from designing the pipe to fabrication is shown. Learn about wave tuning and inertia tuning and how to determine exhaust pipe diameter and length with formulas. A simple method for creating a tapered header. Lots of info for anyone considering building their own DIY four-stroke exhaust system, especially for single cylinder engines like scooters, mopeds, pit bikes, dirt bikes and more. ----------------------------------------------------------------------------------- Tip Jar ( PayPal) : https://paypal.me/49ccscoot ----------------------------------------------------------------------------------- Parts, Tools & Supplies (Some Are Affiliate Links) : Four-Stroke Performance Tuning : https://amzn.to/3v3oNHl Competition Engine Building : https://amzn.to/30hcOrt Performance Automotive Engine Math : https://amzn.to/3ejWK0b Performance Exhaust Systems : https://amzn.to/30gKwNP Slip-On Muffler : https://amzn.to/2PAzFfj 16ga U-Bends : https://amzn.to/3c5XEuw 1/4" Steel Plate : https://amzn.to/3bohqSV Other Pipe/Tube & Supplies From : https://www.mcmaster.com Welder : https://amzn.to/31ue378 Bandsaw : https://amzn.to/3dctDtq ----------------------------------------------------------------------------------- Thank you for watching!
