I think the flanges were like $20-$30 for the pair. Now here is the tricky part, I had custom headers made, 2 inch from head, that way the flanges fit boyh pipes nice sinc the sidepipes had 2 inch individual tubes. If you are still using the factory (junky) joke of a header, cut about 1 inch off the sidepipe tubes, weld them on to the header tubes, you can only slide them up on the header tubes about 1/16 to 1/8 at the most. Weld the tubes solid on the outside on the spacer tubes. Reinstall the headers and slide the plates on the dges ot the header tubes and sidepipe tubes, I used jackstands to hold them at the right height and lines them up with the flanges bolted together, I tacked both sides of the plates in place, disassembled and removed carefully and proceeded to weld the flanges up with full perimeter welds around the pipes. Do a little at a time and let cool as to not warp anything. A little trick is to weld a 3/8 nut on the plate on the header at each of the four holes to assemble them and use 1 inch capscrews with no washers, mine have not loosened yet. Also get some thick gasket material I believe it MR GASKET for header gaskets, come in 12 inch by 12inch sheets, full 1/16 thick, cut your gaskets out with using the plates for templates before tacking or welding in place, promise you won't reget that!! I believe the gasket material was $8 fo two sheets. Also you can use a mig welder to weld the plates to the headers and thestainless sidepipes with no problems, mine nine so far. Let's see that's about$40 max and few hours, but no stinking exhaust leaks PRICELESS
