    I like random tech. cats, Your ory is a 3inch pipe so just make sure you get 3inch cats, Are you gonna bolt them up or have someone weld them?

    We always welded cats at the muffler shop. Too much heat for clamps I think is the reason.

    If you have no desire to run catless ( at the track) then have them welded in. Several header companies make Y's that have cats you can take out and replace with off road pipes so maybe you can have a shop fab you up a set like that. Definitely will cost more but then you have the option of running them or not.
