Iv got the 2.5 inch redback with the single muffler and it sounds pretty good. Its just a cat back so there isn't any noticeable power gain its just noise and its really easy to fit yourself. I got mine off ebay for $190
My auto gearbox in my vx (standard V6) is slipping and being a pain and my mate has offered me his old auto from his vy Berlina.
Can anybody tell me if its a straight swap into a vx or are plugs and bolt ups different?
