Re: XD V8 Duel Exhausts
I've had the same problem. Is your rear section from a van or ute?, because I've never seen a sedan with cut-outs on both sides.
Max you can run is twin 2 1/4 inch all out on right hand side (because of the plastic tank), but this is a very tight fit. Twin 2inch is easy.
Other option is to run the pipes under the diff, but technically illegal and a hassle if you jack your car up.
I'm running twin 3inch now, ending at the diff. Also technically illegal, but is the best performing exhaust I ever had, though it drones a bit at idle.
