Bypassing Cat Convertor
My 156 2.0 TS is of 1999 vintage, with 275 000 Km on the clock.
I'm sure the catalytic convertor in the exhaust system provides little more than back pressure these days. A replacement would be too expensive. Our local regs do not insist on these things (though most new cars do have them). Has anyone removed their cat convertor - replacing it with a straight piece of pipe? A slight bit of power boost may result. -- regards, Malcolm Osborne Sedgefield, South Africa |

Fail / hurried replacement > of cat ?? No, there was a short window where cats were supplied on cars but not required by construction and use regs. It was rather before the 156 though (in the UK) If you turn up for an MOT, the odds are they won't even know it was originally fitted with a cat, and test it (IIRC) as per all other cars of the era. -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) 116 Giulietta 3.0l Sprint 1.7 GTV TS GT 3.2 V6 Triumph Sprint ST 1050: It's blue, see. www.cuore-sportivo.co.uk |

A 2nd hand car just has to get a roadworthy certificate, where they just check basic safety items, such as brakes, lights, tyres. -- regards, Malcolm Osborne Sedgefield, South Africa |
