GrimmSpeed Catted Downpipe 08-UP Subaru WRX/STi
GrimmSpeed Catted Downpipe 08-UP Subaru WRX/STi 
You are looking at a top-of-the-line fully USA built downpipe. All materials, engineering, R&D, fabrication, are straight out of the USA. The tubing is CNC Mandrel Bent 304 Stainless Steel using custom made bend dies which give you the best fit and performance possible. All 3 sides of the 304 Stainless Steel flanges flanges are CNC machined to perfection. If that isn't over-the-top enough for you, check out the new 3-D Contour Flange. Instead of the exhaust hitting a flat wall like on most divorced downpipes, GS have spent a lot of engineering hours creating a nice smooth transition through the wastegate port for the ultimate in boost control for you. The outlet of the downpipe has a standard 3" 2-Bolt flange that will mate up with most aftermarket cat-backs on the market. The convertor is made using a high-flow, 300 cell metallic substrate that will allow the exhaust to flow more appropriately for higher horsepower numbers.
