[QUOTE="Graybeard, post: 1704705, member: 49070"] Now…. Let me sing the praises of the guys down at Full-Race. They hooked me up with the Garrett turbos and their matching billet downpipe adapters. Wow. Look at the pictures. Did I say WOW? This is turbo p Orn. Note that Full-Race’s billet adapters have nearly perfect port matching. As in I don’t think I could do much better with a die grinder myself. Very impressive. Nice and smooth contours, absolutely no restriction here. Looking at the photos of the Garrett outlets with Full-Race billet adapters makes them look gargantuan next to stock parts. The CNC adapters have an ID dimension of 2.560” - a full half inch larger in diameter and massive cross sectional area increase. Surprisingly, these have the same OD and bolt right up to the stock exhaust downpipe. No need to swap out that exhaust or even the downpipe. The only down side of the Full-Race billet adapters is that I had to use Ultra Copper to seal them up. I’d prefer a metal gasket of some kind and Full-Race assures me they have something in the works here. Maybe we can see a matching metal gasket soon.
