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.

Not on a 156 that I know of, but it certainly used to quite common over
here.

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.

Fortunately we don't have such things as MOT in this country. A 2nd hand car
just has to get a roadworthy certificate, where they just check basic safety
items, such as brakes, lights, tyres.
