cutting off cats
just wondering how many people have done it to their v6? does it sound better, increase performance? Also I had an exhaust shop guy tell me not to cut mine off, he said a bunch of crap about sensors and computer problems if I do, is this true? or is he a dumbass, cause he was cutting the cats off my buddies mustang when I asked him haha.

Hey, my cat converters are gone.
Hell yeah it'll increase Hp/ acceleration. Trust me, all that is gonna do to ur truck is have the check engine light on all the time. But you can get an eliminator for the light.
So yeah ur good..
P.s.
Don't pay attention to the Hippie over here worried about the enviroment. LOL

If you have the cat converters removed be sure to retain the O2 pre-cat sensor and the EGR return.Keep it to a low growl and you won't attract a lot of negative attention. Flowmaster 50's will do nicely.
Depending on your state the truck may not pass a smog inspection test.
Add a good high flow air intake system like K&N, AEM or Fram and you will definetly experience better performance. A well filtered street breather modification will keep you intake and injectors nice and clean. With regular filter cleaning or change you won't allow much pollution to escape into the atmosphere. You'll actually burn cleaner and your tail pipe emmisions will be less and you will gain about 20 hp.and 2 mpg.
Good luck.

HELL NO!! Tell me where you saw cheap hi flow cat conv.
And no, they don't add any heat to the cab.
I looked around and couldn't find no cheap ones. even stock are EXPENSIVE.
Plus, i don't think that 45 bucks for the job is bad at all.

And yes the air management done to my truck added all together really impressed me. Sounds nice, and accelerates alot quicker than stock.

Maybe its a, "jeep thing, and we wouldn't understand". LOL
Any one ever gut their cats or core them, I'm going to do this to my Vic, since all cars older then 96 will no longer need testing. And I'm trying to get more MPG out of my truck, will this help?

THE FRONT TWO ARE COLLECTORS. And the back ones is the cats where they have that ceramic or some type of stuff.
And yes all four come down. you wouldn't want to stop up ur muffler.

Actually, that "check enigine light" is becuase you will set off you'r Oxygen sensors. That will 1) make you lose power 2) decrease your fuel mileage substantially 3) continue to throw codes and cuase problems. Theres a reason that light comes on, and black tape is ignorant. You will make your truck run incredibly rich which will cuase all the problems I listed above and things like fouling plugs. I have a 93 f150 with a I6 300 and I took off my second cat and muffler and am putting on a summit glasspack and reconnecting it to the tailpipe so that I get a good balance of power gain, but no engine trouble (my O2 sensors are all in front of/inside the first cat) Plus, all my noise will look stock, and is street legal in my state. There's a reason they call that a "dummy light"
