Any members tell me the part # for a magnaflow direct replacement for my '04 ext cab? Sytem is all stock, including tail pipe. Also, where is the least expensive place to purchase? 5.4 3v, if it matters.

 

Direct Replacement What Exhaust or Converters?

 

Performance Peddler is probably the cheapest. Performance Curve and Summit Racing are quick with top quality service.

 

If you are wanting to simply replace the stock muffler with a Magnaflow you can go with a 12226. It is a 5X8 oval stainless 14" replacement offset in and middle out 2.5" that sounds great on our trucks. They also have a 2.5" I.D. tip and 3" or 4" O.D. if you want to put that on as well. I got mine from performance peddler. I have a sound clip in my sig.
