    Default Quad exhausts on a VT wagon.. Can it be done?

    Hey im currently in the hunt for a new exhaust system since i just put a l67 into my wagon.. I was wondering if i could fit a dual 2.5" system but have quad exhaust at the end like on the new VE's.. Ive seen em on utes and Sedans but never on a wagon. Would my fuel tank and diff pose an issue? Its currently running 10psi on 1.98:1 rockers put ive got bigger plans down the road for it. my current exhaust system if from my old NA motor which is pacemaker extractors through a 2.5" high flow cat into a 2.5: mild steel cat back system.

    also anyone got pics of the black monaro head lights on a white front bar.. looking at them for mine but wanna see a pic first.

    i could always have a dummy pipe on the right hand side for looks. would a dual 2.5 be to much for my setup? or would a dual 2 1/4" be better.. could just find a vy hsv exhaust here dual 2 1/4"

    twin 2.25"(or single 3" for comparison) is only a restriction over 300rwkw iirc

    I was suggested to get either 3" or dual 2.5" for my L67 by quite a few exhaust shops. Most also suggested the dual 2.5" over the 3".

    I would be more inclined to go twin 2 1/4" through twin cats off the extractors.

    Twin tips on each side can be done, but the RHS will have to run across the back of the car between the tank and the bumper. The only issue you will have is a difference in flow between sides because one side will be longer than the other.
