Hello all and happy 2020! I was just contemplating swapping out my cats while the scrap value is good, has anyone done this and are there any recommended brands, tips and tricks?
I figured the better the engine breathes the less likely there will be overheating issues...

 

Always wondered how the XJ12 would sound with modified cats or a cat delete. I modified my cats on my 07 XKR in effect making them into mini glass pacs and the exhaust note is intoxicating! Will follow this thread with interest.
