Soren, I’m using Hooker 3 into 1 headers on my Slant. From the collectors I run 2 1/4” aluminized pipes off each collector with an H-pipe between the two back to a pair of 18” glass pack mufflers then around the gas tank to bright tips.
Rusty is correct, research this issue so you have the sound your looking for. Actually I like the sound from the back of car, at idle to me, sounds like a small V-8.
Thanks, Al
