I've got ceramic coated shorty headers and had local shop run 2 1/4" pipes to the mufflers and then turn downs facing down and out right before the rear axle. Spent $200 for the pipes from headers back including mufflers, labor, tax, etc.. It's somewhat loud and i get a drone around 3500 rpm or so/35 mph . I'd love to run an x or h pipe but with adjustable suspension on the car, i wouldn't want the driveshaft binding up against it. For now i'm driving it and loving the sound. I may have over the axle pipes run with side exits and chrome tips down the road.
