[QUOTE="Canuck714, post: 1485087, member: 6707"] Guys, I was having a discussion in another thread, and thought I would share this here. I have a 14 Roush with Roush exhaust (no factory resonator) and it was unbearable to drive due to drone. I added a Helmholtz Resonator (J-Pipe) back in 2015 but thought I would share how easy this is for those suffering with the dreaded zone in the 1800-1900 RPM range. I think I was in the 27.5 inch range but should probably be 26. Below is the calculation for the length you need to cancel the frequency at a specific RPM. As well as a picture under my truck to show how easy it was to run it along the side of the exhaust pipe. [ATTACH=full]144438[/ATTACH] [ATTACH=full]144439[/ATTACH] [/QUOTE]
