Blitz NUR Spec R Systems come with removable exhaus tip silencer:


The design and construction of the NUR Spec R exhaust is second to none. They are engineered from mandrel bent SUS304 grade polished stainless steel, with computer controlled precision fishtail welding.

Most silencer boxes have a 115mm sized tail pipe and some systems come with a removable baffle section. The choice is between a big power gain, and a deep, loud throaty noise, or medium power gain and a more modest sound.

With a 76mm bore which runs from the catalytic converter back (on most cars), the Nur Spec R series are finely engineered to give good power gains, especially on turbocharged cars. Particular attention is paid to minimise the length of the path from the turbo to the exit pipe, which greatly helps to reduce back pressure.
This is ideal for cars with boost upgrades as the standard exhaust can become overly restrictive resulting in a loss of performance, and undue strain placed on the turbo.

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

The BLITZ NUR - Spec Series exhaust systems are available as direct bolt-on replacements for OEM exhaust systems. Blitz exhausts reduces back pressure and thermal stress. This allows the engine to create more power and torque by breathing easier. By utilizing extensive computer controlled design, flow analysis, dyno testing, and precise fitment, The BLITZ exhaust systems produce maximum horsepower without dramatically reducing low-end torque.

The quality of the BLITZ stainless steel exhausts is second to none. Rated as the highest quality, Blitz 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 Blitz 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.
