Gots lots of sugestions.Tuck the mufflers as high as you can. When I drop my air bags, they scrape the pavement. I use the rams horns also with a balance tube between the pipes just ahead of the 40 flowmasters. I exit thru the roll pan beneath the tail gate. Bad Idea, the exhaust has stained the whole tail gate from pearl white to a pearl beige. and I'm not burning oil. If I had it to do over I would exit in front of the rear wheels.
