Hi, anyone tried the Swallows Racing Sports cats?

Did the exhaust many years ago, have a Milltek stainless full catback system. But think there is still some sweet deep v8 burble to release and hope to find it by replacing the old stock cats for less restrictive ones.

What product did you get? They don’t list anything for Jaguars.

 

I found this: https://swallows-jag.co.uk/product/s...l-sports-cats/

Also see now that Paramount sells 200 cell cats, as opposed to Swallows 300 cell cats. But Paramount cats are way more expensive

 

I noticed that it indicated you’d need to have your ECU remapped?

 

That's not how I interprete it. My guess is that on a 4.2 Xkr you will get the most out of it if you also do a remap.

On the 4.0 on the other hand the ECU is self-remapping to a certain degree. My car is a 4.0 Xkr

 

Thanks all - appreciate the posts !
