RE: after cat pipe
there is the turbo, then the cat, then the flex pipe, then just pipe...... if you have 2 feet of gap you have alot of corrosion.......
if it is legal, i would do a tp, then flexpipe and have a shop make you some 2.5 in exhaust pipe all the way back to at least the stock muffler, but that is me
