Trying to finish up my exhaust modifications tomorrow or Thurs, figured I'd post a video of the "before" I get out the saw and welder, lol.
What you'll hear here is an all Magnaflow setup:
High Flow Cats, removed y-pipe and replaced with an x-pipe for true duals, two 14" oval Magnaflow single chambered mufflers run to a pair of 3.5"x18" rolled edge tips.
Tomorrow I'm going to cut out the high flow cats just to see how it sounds and performs for a week or so, then depending on what I decide I'll either weld in my "replacement" pipes or remove the pre-cats and put the high flows back in so I only have 2 cats, why Ford decided to put 4 on these beasts I don't know. I'm sure there's a logical explanation.
I'll update with new exterior and in-cab clips after tomorrow/thursday.
