Morbid Intentions

a guy told me what to do next with my 04 stang, he works for jack roush so I think he knows what he's talking about but they were things that I don't hear alot about on the forums
he said my check engine light was robbing me of ponies and the first thing I should get is the O2 sensor eliminators (because of the cat's being gone) and then the next thing I should do is get the X-pipe that bypasses all 4 of the catylytic converters up front?? ( I have no idea what pipe this is and help wouuld be appretiated with a link) and then I should get the stock computer tuned because the my exhaust setup will be so free flowing that I will lose a ton of backpressure and since I'm getting tuned I should do 4.10's with the
X-pipe/// after all of that he claims I should do about mid 13's... I was skeptical but with my times with the check engine light on and regular eagles I have no reason to doubt it

pretty much means get an off road x pipe (the one with no cats or resonators, just pipe) and MIL eliminators and a tune. a handheld tuner get also get rid of the cel

cel? he said something about the exhaust going back into something to save gas or something like that ... is that what that is called? he said to take it off also if that's the case

ALL of the things you mentioned are CONSTANTLY talked about on here....lol

"Bypass cats" = Off-Road mid-pipe
"CEL" = Check Engline Light, used MIL's to get rid of it or a handheld tuner
You DO NOT need a tune after installing exhaust, although a dyno pull to see you a/f would be a good idea.
4.10's can be compensated for with the tuner, and a re a good mod, but are by no means necessary.

I have a buddy who works for H&K and knows squat about guns, so I would take it with a grain of salt.

Oh, and the burnt exhaust gasses get re-ciculated into your INTAKE, not your gas tank


Oh, and your magnaflow magnapack exhaust is a catback...it has nothing to do with your catalytic converters, so you can take that part out of your sig.

remember you don't need both mil's and a tuner. the mil's don't work anyway. i used mine for 3 days and took them off and since then my cel hasn't came back on, and i didn't turn it off with the tuner.

weird. Mine worked just fine....and still are.

I didn't even NEED them, had an 02 go bad and MIL's were cheaper than ONE new 02 sensor.
