Catalytic Converter Question

[walnuts4x4]

I don't have a check engine light on and my rears have been deleted for over 2 years

Sold by the same company

How can they say that there's no such thing on one section of their site and then on another section... SELL high flow convertors???

It doesn't appear that they sell them, when you go to that link, they have no cats listed for sale. Link: http://www.discountconverter.com/dynomax_catalytic_converters/all_dynomax.cfm

Like I said, all of my catalytic converters are behind my 02 sensor, not in the middle. So therefore, if I plan on eliminating my rear two cats, it WILL throw a check engine light.

weird must have changed them around since me, KWT2000 and soldier777 have done the rear delete without a problem

My O2's are ,2 in the front of all cats and two behaind the Cats, I'm sure this is the way all Expys are setup. The rears monitor if the cats are working properly.
My exhaust shop guy has done numerous rear deletes and high flow cats and says he never gets a light on. He guarantee it.

i have a 99' expedition and my 02 sensors and catalytic converters are bad, instead of replacing them can i just run straight pipes and get better performance?
when i drive it, it putters and very annoying!
will the straight pipes make it run better?

How do know your Cats are bad ?? Are you getting o2 sensor code ?
