Sportex exhaust decat pipe Honda Civic 1.5i 1.6i 1991-2000
Sportex performance exhaust decat pipe designed to fit Honda Civic 3 door hatch (1.3i 74bhp EG3), (1.5i LSi 90bhp EG4), (1.6i ESi 123BHP EG5), 1.6i VTi 156bhp EG6) models built 11/1991-1995. The de-cat pipe or cat replacement pipe (they are the same thing) bolts in place of the original catalylitic converter (cat).
The Sportex exhaust De-cat pipe is basically a pipe the same size and shape as the original cat. 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 found toward the front of the car exhaust after the downpipes and before the system. This part bolts to the system using 3 bolts.
NOTE: Decat pipes will not pass an MOT on cars produced after August 1992.
