The design and construction of the Nur Spec R exhaust is second to none. They are engineered from SUS304 grade polished stainless steel, with computer controlled precision ‘fishtail’ welding. The pipework is mandrel bent which maintains a constant diameter throughout allowing superior flow.

Nur Spec R exhausts are designed for maximum performance, amazing appearance and an aggressive exhaust note. Most silencer boxes have a 115mm single tail pipe and come with a removable rear baffle section, which is easily removed and replaced by just removing a single 10mm bolt. The choice is between a big power gain, and a deep, loud throaty roar, or medium power gain and a more modest sound. In recent tests a Japanese 2003 Impreza had noise levels of 96db with the baffle inserted and 105db with the baffle removed. By using state of the art computer design, flow analysis, dyno testing and precise fitment, Blitz exhausts produce superior power gains without dramatically reducing low-end torque.
