no no no im saying the 2.5 inch flange does not bolt up to the 3 inch flange. a 2.5 and a 3 inch dont bolt up together thats why i need the reducer so the 2.5 end can be welded to the catback and the 3 inch side can be bolted to the downpipe. and theres not exhast leak from the headers its in the middle from where the flanges are suppose to bolt together. . . that is the only area where it isnt connected properly. argh lol
but anyway i think i found some parts after saying forget 3800 sites and lets take a look in to other sites.
