200 Cell HP Cats for XJR
Hello everybody,
i'm planning to build up some HP Cats for my XJR.
The plan is to use 200 cpi metallcats because i dont want to get problems with the lambda sensors and they should fit nearly p&p ( on the exit i want to get 2 1/4 or 2,5" but at the moment i'm not sure if 2,5" is required)
My first step is to measure out how my space i have, to decide which shape i chose and to design the connecting plates.
If you have some additional ideas for me please feel free
Best regards from Munich

Nameless Performance do 200 cell cats for our cars
https://namelessperformance.com/
They've been covered quite a bit in the XK forum, but a few people have used them on XJ's as well.
Hopefully someone with some actual experience will offer some useful advice about them, as I see they have two versions listed on their website for XK's, but nothing for XJ's

Sorry, I have a 2000 XJR. I bought the cats from Waterdragon when, I believe, he couldn't pass emisions testing in California. They are ceramic coated, which is nice. I am adding a 2nd exhaust gasket to the bottom connection because of a bit of leakage. If you do a search for "nameless cats" and "Waterdragon", you should be able to get more details on the cats.
Hope that helps.

Mine is a 99 XJR - quiksilver 2 1/2" system plus nameless 200 cell cats - I bought the cats a few years ago to suit a XKR, (that was all they supplied them for back then) XJR and XKR cats are identical in all respects, I had them fabricate them with 2 1/2" outlets especially -
I have always thought I could have spent that $1,000 more wisely.
I also had alignment troubles using the solid copper flange gaskets they supply, ended up using OEM gaskets
Cheers
