How low is the truck. The height will affect the sound

I'm Goin to try it with the 90* turn down. That way I can test other stuff with it. If it's quiet, I'll ride with it. If it drones or something I don't like I'll shorten it and put a 45-60* turn back on it instead.Don't do the turn down. On a lowered vehicle it'll drone like crazy. I did some in front of tires with turn downs and it was loud as fak and drones crazy. Lucky me I whacked one coming into a driveway and ripped it off so the other one followed quickly.
On my diesel I have a 4" and the mandrel over axle had this sweep that rolled the tip kinda down kinda back. I got some resonance so I slashed it to it faces 90% side and that solved it. Good luck
4.5" on a 4cyl? That's a whole lot of exhaust flow for that little motor.I had a full 4.5" Turboback exhaust on my 2002 Subaru WRX. Turbos love big exhausts if you can get over how loud it'll be. Building this truck for performance I assume?
