I just installed my throley headers last night and the ypipe at the collector is hitting (not quite about a paper sheet above) the frame rail. Has anyone had this problem...if so how to fix? I have thoguht about adding a small wedge or even a second gasket between the header the ypipe flange and try to angle it up...just havent had a chance to try it. Any help would be great, want to get this cured this weekend so I can get the collector flange welded to my cat. Thanks.
