How far do your tips stick out from the body? Stupid question I know but I'm getting my exhaust put on tomorrow and I like yours. Look to be an inch and a half.

if you remove the cats, wont that fail emissions?

[DarrenWS6]

yes.

[saosurvive126]

A lot of the Fords had 2 sets of 2 cats (4 total) and the back pair is usually after the oxygen sensor, so no check engine light. And I know that in a lot of states they just plug your car/truck in if its1996 and newer.

[krazycardude]

What do you mean they plug your car if its 96-up? and what is the song?

[saosurvive126]

Instead of hooking a hose up to your tailpipe to test emissions they just plug in to the OBDII plug and check for any engine codes.

Oh and the song is "Right Now" by Korn

[krazycardude]

Oh, ok thanks and thanks for the song info too : )

What kind of MPG increase have you seen with the new exhaust?

[DarrenWS6]

15.3mpg before exhast, 16.2 after, no other modifications between those checks, and the tire PSI was 35 all around. I've recently moved it up to 40 so i'm expecting it to be a little better, and planning to cut the rear cats out soon so its only running two cats.
