Talked to Rick Miller at SEMA and he was eager to do these. Got them back today. They cleaned up amazingly well. 26% increase in flow according to their data. Hard to photograph much of it to show the inside surfaces but you can get the general idea by looking at the larger inner surface areas near the turbo flanges.. The entire interior surface area looks like this. Thanks Rick for a job well done. -Rob
