    Hi Guys,

    I have tried to search google and this forum for a definitive answer to my lambda issue. Does it have one or two? I am wanting to order this de cat pipe and they offer a welding or lose option where i fit it. But do i have one, therefore do i need one?

    AUDI S3 & TT 1.8T QUATTRO DE-CAT PIPE from JOHN ASHLEY EXHAUSTS | eBay

    Thats the ebay site, the business is John Ashley Exhausts. I have phoned him and he wasn't 100% sure.

    Thanks for the help,

    J

    Has two sensors... one (wideband sensor) in the top of the down pipe and one (narrow band) just after the CAT...

    You will only need one boss in the decat pipe
