I have a custom magnaflow system from the headers back. A guy i know wants to trade me his factory system plus some cash and will pay to get it done at a shop. Anyone know how much it would cost to get our trucks both in the air unbolt our systems and sap them? Btw the shop i went to charged me 150 to get all my cats cut out and maggies welded in then welded in 2 magnapacks then welded my 4" tips. so that may help with the guesses on how much it will cost
