The Hyperflow Exhaust Turbo back Exhaust for 2001-2007 WRX and STI packs a powerful punch. Offering huge power gains over stock and a awesome exhaust note to match it’s distinct Race N1 Style Muffler. Full 3 inch from the turbo all the way out to the tip, rest assured this is the last exhaust you will have to buy for your monster capable of flowing enough to support a 700whp Subaru.
Made from T304 Stainless and polished to a mirror finish. Not only does this exhaust offer pure performance gains but it also aggressively styled but built with quality in mind.
To complete the Turbo-Back system, it is supplied with the new two-piece catted downpipe which uses a massive cast 304 Stainless Steel Bellmouth that tapers to 3.0″ piping where it connects to the 100CEL cat-pipe. This setup allows you to swap out the cat-pipe for a catless racepipe without replacing the entire downpipe assembly.
