Blitz NUR-CTi Axle Back Exhaust Subaru WRX STi 04-07

The quality of the BLITZ stainless steel exhausts is second to none. Rated as the highest quality, our exhausts perform as well as they look. Unlike conventional exhaust systems, BLITZ exhausts utilize a slanted mounting design which eliminates unnecessary bends. The specially designed muffler and large diameter mandrel bent piping has no reduction of inner diameter in bend areas. The constant piping diameter size allows for superior exhaust flow superior then compared to crush bent piping.The most impressive feature of our exhaust system is the quiet tone with the silencer on, and its aggressive tone with the silencer removed. Performance increases very by application (gains of 5 - 20 horsepower are average). BLITZ exhaust systems are designed for maximum performance, improved appearance, and an aggressive tone. Each BLITZ exhaust is flanged and comes complete with all gaskets and hardwear. Providing the easiest bolt-on installation possible. All BLITZ exhaust systems utilize factory mounting points and hangar locations. A fine balance of looks, power, and durability has been achieved through full stainless steel construction finished in a show quality shine.
