I'm looking for some high flow cats without draining my wallet. I have a 2002 Z28 and I live in AZ.

If I get two of these do you think it will throw a check engine light or will it be fine?

And BTW I'm getting longtubes and that's why I'm replacing the cats at the same time.

 

I would look for 3" ones if I were you, esp. since it's a V8!

 

what long tubes are you getting? most companys offer a cated y-pipe.

 

deff 3"

 

Really 3 inch? So would that mean that I would have to do 3 inch all the way to the 3 in collector? And I'm looking at some pacesetters right now.

 

i would do the biggest headers you can get with 3 inch cats and X pipe run true duel straight pipes

 

Now you're talking. I would do this! Greetings from Mesa!

 

must keep cats or you will end up in the situation like im in with no cats and no licences plates because no one will pass me even though im trowing a code. they just look under the car and tell me wont pass it so now im looking into buying a 3in cat to put in after the y pipe. f emissions

 

I was going to do 2.5 in from the cats to the collector because I heard that ground clearance was pretty bad with LT's. Is this correct or is that .5 inch not going to be that big of a difference?

 

Ok and also they have some 3 inch cats for the same price. My main concern is if I'm going to throw a check engine light, and if I'll pass emissions.

Thanks
