Sportex exhaust decat pipe Vauxhall Nova SRi GSi 1992-1994
Sportex performance exhaust decat pipe designed to fit Vauxhall Nova SRi GSi 1992-1994.The decat pipe or cat replacement pipe (they are the same thing) bolts in place of the original catalylitic converter (cat).
The Sportex exhaust Decat pipe is basically a box or pipes the same size and shape as the original cat and are ideal for fast road or track day use. The cats function is to clean exhaust gases that pass through its cells it's these cells that cause the restriction to exhaust gas flow. Sportex decat pipes are far less restrictive which vastly improves the exhaust flow allowing the engine to produce more power. Each Sportex decat pipe is hand built on individual jigs ensuring a perfect fit. The material utilised in production is mild steel which is aluminised for corrosion resistance then painted. The standard exhaust cat is usually found toward the front of the car exhaust sometimes in the front pipe below the exhaust header on other cars it's in the system. Some performance cars usually those fitted with a turbo charger can have two cats. Decat pipes will not pass an MOT on cars produced after August 1992. For optimum power gain fit with an induction kit and full exhaust system.
