    2.5" in/out cat?

    did and bmw's come w/ a 2.5" in/out cat? I am going to need one for my turbo set-up for my "high flow" (ie straight pipe) cat. Oh and it needs to be a single in/out.

      Some of the V8 cars perhaps, or e46 M3 (cats are in the downpipes ~6in from the head)

          Why don't you just leave the cat out entirely? We don't have to pass emissions after Jan 1, 2006.

            I think he means he is going to hollow it out and put a pipe through it so he can pass visual inspections.

                Catco ones are on ebay for $36, magnaflows are on ebay for $52 i believe. ebay is definitely cheapest place. I got catco cat, its good enough for 6.2L so it will be plenty for our cars and im sure its hell of alot better than what its got stock.

                        you think you could put in a glasspack where a cat should be and say thats a cat
