New Exhaust for my Duster?

IF, (Big word there if....) IF the current welded pipes are good, not cracked, you can just cut off those things on the end and install some mufflers. From there, it'll be your choice of over the axle pipes to the bumper or 90* bends to exit infront of the rear tires.

Your call.

OH, that there looks like a 340 exhaust manifold. Is that a Edel. Performer intake? W/EGR valve or stock intake?
