what kind of MPG are u getting?

[DarrenWS6]

At the time I was seeing 15.2 - 16.5 average, and 20.4 highway custom tuned. Now that i'm running 20" XD Monster wheels with 33x12.5 Toyo Mud Terrains its getting 14 - 15.2 average, 17 highway.

[Robskie13]

is yours 4wd? did use edge programmer?

[DarrenWS6]

yes, and no but sorta, it was a custom tuned edge, called PHP Gryphon.

a man like the exhaust just got me, a 06 f150 with the 5.4 have been looking for a exhaust i want something that gets attention, lol im stuck between pypes and flowmaster super 44, have heard anything bout the pypes setup?

[DarrenWS6]

Pypes isn't talked about much except for the Corvettes and such. Super 44 will sound pretty good.

[DarrenWS6]

yes it will fail. Even though the trucks 5yrs old and is now ellidgable for catalytic converter work, the exhaust give a slight silfer smell and it smells strongly of it at start ups. It will for sure fail the sniffer test.

[HystericPoison]

also, with the cat removed after the o2 sensor, will you fail emissions, even though you still have the other two (right?) catalysts?

[DarrenWS6]

Thanks. Nope stock intake here. I want to maintain good economy so I said nay for an intake. I'm now running a Gryphon programmer and burning 93 fuel.

[HystericPoison]

that is one badass exhaust you have. do you have an intake? i have the 3.5" AF1 and waiting on the tunes. trying to figure out what kind of exhaust i want. i really like the way yours sounds.  props! (i also have the extended cab 5.4 4x4 except mine is blue)
