Who is the MANUFACTURER of the 2011 Jaguar XJL X351 5.0 V8 Catalytic Converter?

 

Not sure. However, in the US, Magnaflow was the only manufacturer I could find on the CARB-compliant list when I last checked. As a Californian that significantly limited my options.

According to your profile you’re in NJ, which is also a CARB state. So if you want a legal cat, it may also be your only option other than the dealer. At the time Hoonigan sold it for much cheaper than Magnaflow.

 

FYI, I still have my used one (drivers side, direct fit) that still works fine. If you want to save some money, I’m willing to sell for $100 (scrap price) + shipping.
