I bought my Z with 36,000 miles from a 70 year old golfer in Naples, FL. My First upgrade was replacing the catalytic converters with test pipes, and my O2 Sensors got stuck in them when I tried taking them out, I tried briefly, they wouldn't budge, so I VERY quickly gave up on taking them out. (The heat nearly welded them on, I was told it is common with O2 Sensors). So both the cats and O2 Sensors only have about 38,000 miles on them. (No more than 40,000, I took them out the in December, they've been in the garage ever since).

Bump, these cats might as well be new! The old guy that drive my car before me was the type to never take it out of third gear! Never abused.

 

these will NOT work on a 2004 DE non-revup right ?

 

Nope 03-06 cats are different from 07+

 

That is correct, the cats are different.

How much would it be install these. I have art test pipes due to a bad cat on a 07. The test pipes are killing my gas mileage.

 

I'm getting 13/25 mpg with test pipes. How much would I get with the OEM cats?

 

Well before I took them out, I was in the 22-28 range depending on the driving. With Wide open throttle and heavy throttle during one tank, my computer never went below 17 mpg. I averaged 19 city (five minute traffic lights) but depending on my driving overall was between 22 and 26/27 but if I didn't mind taking my time to be OCD, I've gotten as much as 32 according to the computer/multi gauge. Mileage on those tanks reflected it as well. Keep in mind Florida is flat though.
