I have a quattro 2.8 30v 1998 (engine code AHA).

Both cats on my car are rattling really bad so I need to replace them. I don't want to put original parts on it because obviously they're too expensive. I just want to get 2 universal cats or high flow cats, weld them and be done with it. What I'm worried the CEL. Is it going to light up with two aftermarket cats? If any of you guys have any experience with these kind of cats let me know.

I don't care about emissions test because I live in canada and we don't have them yet. I just don't want the CEL.

 

i put a HFC on and a borla exhaust system on my car a bout a month ago and i get a CEL because it thinks my cat isnt doing its job but there is a fix yo make the CEL go away. i have the parts but i just havent had the time to do it yet. check this out http://www.scoobymods.com/forums/showthread.php?t=5468

 

I'm completely stock right now, I don't want the CEL to light, it annoys me alot for some reason. If a HFC will light up the CEL, is a "normal" universal cat going to be ok?

 

umm i cant be positive but i dont see y it would give u a CEL
