Great Value for the price
Very well constructed for the price point. Hubcentric V-bands are very nice quality and huge help when dry-fitting hotside piping. No complaints thus far, Will complete piping and resubmit final review

Headers
Headers still aren't installed but they seem well built for the price point. My beef is with the v-band flanges. These are not standard flanges. They are hubcentric which is nice if you plan to use the provided flang, but I was going straight into a 3" to 2.5" reducer that was machined with standard v-band flanges. This part doesn't work so i'll be using the provided flange. Not a deal breaker but should be known. Also, plan on picking up a couple of 3" clamps because the clamps in the box need to find the trash bin.
