Gents.

We all know that the CAT is a BIG restriction in the exhaust system. I run my truck less than 5K miles per year, so I'm emissions exempt. As such, I want to gut the cat on my 1997 Ram with the 360 (4x4, automatic) before I install a Flowmaster cat-back system. I figure with the cat gutted it should sound good (but I am a flowmaster fan).

My question is on the CEL and how it will be affected. I know there are O2 sensors fore and aft of the converter, so I'm concerned that after it's gutted I'll have to deal with a CEL.

I would assume the CEL will be on after I gut the Cat, so how do y'all get around that? How is that generally handled?

Thanks for any tips anyone can provide.

-Greg

LOL, that's awesome man. Good deal..... 18MM plug non-foulers here I come! :)

Did you use both and only drill out the first one or just use one CMH?
