If u r looking to save $, get u a pair of hi flow cats, have an exhaust shop cut the 2 front cats off and replace the rears with the hi flows. Then pick up a dual in dual out single magnaflow muffler and have it welded it at the same time. Unless u really care about having shiny pipes, no reason to spend $700 on just a cat back. The above procedure is what I had done on my truck. I had maybe $450 total in the exhaust and that is including the price of the muffler and the cats. That setup sounds awesome in my opinion. I ended up going expensive and I had to buy a bassani mid pipe because the flanges on my old stock exhaust setup were jacked up and started leaking after while. If not I would still have the above setup.
thanks tt1981 but the muffler shops by me are good shoemakers. Just my luck usually runs that as soon as I buy something someone tells me "oh XYZ auto has that for 30% off". Figured I'ed fish a little before dropping 1600
Lethalperformance, create an account on their website and you will see magnaflow prices discounted a very good bit. I also know marylandspeed usually has 25% off on magnaflow, they only show the catback on their website though. Code magnaflow25
