The design and construction of the Nur Spec (S) back box is second to none. They are engineered from mandrel bent SUS304 grade polished stainless steel, with computer controlled precision ‘fishtail’ welding.
The Nur Spec S is a rear silencer only, it fits to the standard exhaust sytem, without modification.
All Blitz Nur Spec back boxes conform to the Japanese JASMA regulations. This means that all back boxes will give a noise below 96db, but most Blitz boxes give between 92-96db on a standard car.
Note: Nur Spec S is not interchangeable with Nur Spec R.
