Read through the sticky about the xs power downpipe and decat for the s3, got a few questions before handing my cash over.
Is it a straight bolt on to the original k04 mani? And the standard cat back system? And I know when fitting you remove the post cat lambda and this throws up an error but with the 200cell sport cat do you still fit the post cat lambda? And does it throw any errors?
