Hello there.....i too have a Toledo 20v turbo I am starting with 1 of them downpipes off ebay with the sports CAT. You must have seen them....around the £230 mark but i won 1 they put in an auction for just over £100. It looks to be good quality stainless steel and is 2.5 inches in diameter. Next week i am having it fitted using a reducer as i cant afford the cat-back piece yet.
From what i have read there is no need to go bigger than 2.5 pipewirk on the AUQ engine. I think the standard zorst is 2.25 inch diameter, but before i have the reducer made up, i am gonna get underneath and measure it just to make sure.......
