I went on ebay 2 weeks ago searching for a cutout to install before the cat. I found a 2 1/2 stainless complete system for $108!!! I couldnt pass this up. It came in 10 days after i bought it. I had it welded on so that the cut out dumped to the inside area where the origional cats were and the cat was moved back 11 inches further but still within the shield area. the pipe went in 2 90degrees to the center then to a 3" borla bolt on system. IT IS INSANE!!!!!!!!! It is made by Raceland.
