I have 3 1/2" tips coming out before the rear wheels. I used an exhaust hanger and bent it until i got the right angle, then i ran flexpipe up to my mufflers to hook them up.
They look good and sound great, the big tips and Thrush turbos give it more of an old school sound. But, I was thinking of routing the pipes straight out the back instead, I'm still undecided.
