Borla Stainless Steel header for 1999-2001 2.5RS. I've used this header for three years and it's been great, but I've got a new equal-length header now. I don't know if the Borla makes more power than stock, but it weighs less and it sounds cool. It also throws a CEL. Since CELs don't bother me, that hasn't been a problem. $200 or bo. -- Larry B.
