miltek cat back

in the future i will be getting a remap is it worth paying the extra for a cat back milltek. does just the middle and back box give you any more bhp on a b5 rs4

The biggest gains will be achieved by removing the precats (or even main cats) from the downpipes, but there are also some restrictions in the OEM middle and back boxes.

If you're going to do it, I would go the whole hog :thumbs:
