Ive made my booking and its quite a reasonable price. £150 for CAT back (with my current backbox) and additional £50/60 for turbo to CAT pipe. Il let you all know how it goes!
also topgear use better quality s/steel than powerflow, so it doesn't rust...
Autowise in Burgess Hill, West sussex
mines stainless throughout, been under the car and checked it myself.....i payed £220 ish for it.
Have you done the magnet test?
Higher quality stainless steel, which has less chance of rusting, is non-magnetic. I think you'll find Powerflow systems are magnetic, whereas Longlife systems are not. Although, I think my Longlife system was a bit on the pricey side.
The following is taken from here
"A basic stainless steel has a 'ferritic' structure and is magnetic. These are formed from the addition of chromium and can be hardened through the addition of carbon (making them 'martensitic') and are often used in cutlery. However, the most common stainless steels are 'austenitic' - these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it non-magnetic."
