not sure of any pre made kits that include cats for these cars, best bet is to pick a kit you like in your budget & just add cats to it. pretty sure most companies like dynomax etc make a high flow cat. & im not for sure on this but do cats eliminate exhaust "odor"? always thought they were more for emissions of the bad things in exhaust... i know my modern cars with cats still stink pretty bad, its the tune of teh carb that makes the biggest difference in my experience, ive had cars that run very rich & will burn your eyes after just a short time of running in the garage with the big door open, can even leave small black spots under the exhaust tips on cold starts. so make sure the tune is spot on, maybe use an AFR meter & that should help the odors.

ive used the pypes kits & they fit very good, the X pipe is supposed to increase power but does tame the sound a little. i did buy a dynomax high flow cat for my old daily driver jeep that didnt need high flow but was a lot cheaper than buying an OEM one.
