Just took off my Cats and i got a question

ocsailor86 · October 17th, 2007, 11:44 PM

YEah so i just took off all my catalic Convertors today and i installed the X pipe that i ordered from jegs. Im pretty sure that my cats had carbon build up so it wasnt running right. So will i see a big difference with the new x pipe with no cats?

You would think since theres nothing blocking the airflow now, but I'm not sure. Hope you get your question answered.

offroad x pipe and h pipe makes less power than say and after market pipe with cats, but you will definatly see more power than stock

You'll see improvement. But until you get some other stuff built up and flowing better you'll only pick up a couple HP. Have you shut off your rear o2 sesors yet or did you get Mil eliminators? Because you shoul d be throwing a CEL by now...

ocsailor86 · October 18th, 2007, 11:35 AM

No i dont have the eliminators. So im throwing a light. But its ok. Ill buy them soon. So what mod do you think i should go with now? Intake? or what?

HMUSN · October 18th, 2007, 11:37 AM

JLT if your going to get an intake.

than save up for a pi swap.

G.T. Rags · October 18th, 2007, 12:26 PM

Docs right, PI swap or Bust in order to make decent numbers.......

No swap and no come close to 250 RWHP

AnglicoGT98 · October 18th, 2007, 01:15 PM

+1 with HMUSN. JLT is the best! But you might as well do the T-Body and Upper Plenum too. And then the PI swap. I'm doing one myself in about a week. I got some MIL's if you want to pick them up off me. I have no need for them. PM me if you're interested.

I think you will notice a huge difference !! I have A 96 GT with a 8lb vortech supercharger and ran it a while with the cats on and then took them off about a month after i put the charger on and I noticed a HUGE difference !! Hope it works the same for you!!!
