[jimbob-mcgrew]

nothing harmfull if thats what your thinking.

exhaust gasses will flow better without its restriction

[stockcar123]

would it increase power

[millworm]

If you replace with a straight pipe yes it will

What engine is it, as I took the cat of my 1.4sri and never had a problem it increased power and run sweet as a nut from mot to mot

[Stuart]

Very small increase in power.

[burgo]

You need a cat for the mot now

[bazzap8389]

Not on a pre 92 (j reg) petrol? All diesels that had them from factory will fail without one though.

Just knock the inside of the cat out problem solved

Just knock the inside of the cat out problem solved

Only problem with that is it's not a direct flow so would not make any difference unless you cut it in half and welded a straight pope through the centre

[turbojolt]

be easier to just give the mot tester a drink then

If it was a 1400/1600 MPi do it. Otherwise don't waste your time/effort doing it to a 1200/1400 SPi.
