Magnaflow Exhaust

Dixie Design · #1 Tue, January 6th, 2009, 04:02 PM

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.

Man, does that sound nice or what? Good job on that! It's got a nice note without being loud and obnoxious.

No doubt about it, Magnaflow does make a nice setup.

Cut out my rear cats today, I'd SWEAR my truck's quieter now. What gives!? I'll post vid clips tonight!

Hey Bill, What exhaust do you reccomend for 08 F150 supercrew 5.4 for daily driver and light towing? Looking for HP and MPG but still fairly quiet. Going to get a Gryphon with your Custom 87 performance tune but think I should get exhaust first, no CAI planned. What have you seen work? Single exhaust is ok . Thanks: Jim

Corey made a great recommendation there! I know you're asking Bill, but I'll chime in too if you don't mind

The first exhaust mod I made was to replace my factory muffler with a 14" SI/SO and really liked it. With your truck having only 2 cats as opposed as the 4 mine came from the factory with, you'd a bit louder than I was with the SI/SO swap. A magnaflow SI/DO would be cost effective and sound even better! I'd probably stick with a 14" or 18" certainly nothing larger if you want more sound.

Thanks for the quick replies Corey and Dixie, sounds great but I am looking to not be too loud, what do you think. Jim

I'm not psychic :crystal: or anything. I know this because I'm the one that gets those phone calls every day asking what we recommend. There are some standard things that Bill likes -- one of them being the Magnaflow SIDO exhaust.

....that's what I got. Even after having for a 14 months, it still makes the hair stand up on the back of my neck. It may not be the absolute loudest but it's sound is intoxicating.
