i just got the cheap autozone ones with the paper in between the two pieces of metal. i used copper RTV silicone on both sides and installed. so far so good. i check every now and again for black signs of leaking and listening for hissing etc. i got them over OEM because 1. they were thick and i noticed my header flange was not 100% flat (manual says its fine as long as the flange isnt warped over a certain amount, a few 10th's which mine was) and the paper thin OEM metal ones may have leaked. 2. price was 1/4th OEM.
