I've just had a new full stainless system built so have a centre section and stainless performance rear box for sale. Both have only been on the car for around a month / 250 miles.
The centre section should fit all v6's (2.0 & 2.5l), but please check the part number for yourself - AS12284. £30
The stainless rear box was a little loud for me, but is very well built. It's got adjustable tips so you can get the tailpipes to sit nicely and is 2.25 inch (57mm) internal diameter. £45
Or £65 if you want both of them.
Collection from Chertsey, Surrey. Let me know if you need any more pictures of info. Delivery possible if you live on the route between Chertsey and Worthing by arrangement.
