I removed the 200 Cell Sports CATS from my 4.2 XKR before it went off for sale. I havent done the photos yet, but they cost me £1,200 3 years ago, and will take £500 for them, professionally made. Sourced, fitted / removed by the team at Powerbell in Taplow. They give a much cleaner flow; improved response and much deeper exhaust note (I never had a cat back system - just used these).

Direct message me and I will send you my contact details / photos. I live in SL8 (Bourne End, Bucks)
