Exhaust Help

I think the flowmaster american thunder exhaust included whats called super 40 or super 44 mufflers. If I'm correct I'm sure you can just buy 2 of them and have a muffler shop weld them in for half the cost of a full cat back all in. My advise is go directly to the source (flowmaster) and inquire about the mufflers. If my above statement is accurate price some things out and go from there. Personally for me time is also money and I only mess with cat backs. Reason is I'd rather pay full price for perfect fitment then half price and end up having tips sticking out 3 inches looking like a pep boys special so make sure you tell the shop to mind the tip length if they cut out and weld in product for you.

Find out the inside diameter of your piping. Make sure this is the inlet/outlet size of the mufflers you order. This will make install easier. My recommendation is to replace the resonators with the mufflers. This will depend on how much space is at that point in the system. Also, keep in mind the varying lengths of mufflers. That will also be involved in determining what part number will fit.
