King_prawn 0 Posted May 29, 2003 I assume these Cat replacement pipes are just a straight through piece of pipe. If this is so, then what happens to the Lambda probe? Do they just cut it off, or do they somehow plumb it back into the replacement pipe? Cheers, Rob Quote Share this post Link to post Share on other sites
