Catalytic Converter, Opinions? Options

[Chucky]

Hey guys!! I was wondering if there really is a big need for the converter. Would anything bad actually happen to the performance of the engine with not having the converter? Cuz mine's like rusted up and I'm thinkin', why not just make it a straight piping all the way to the muffler! Gimme your opinions.

Actually a cat can cause you to loose up to 10% of the power of a car. On some cars it is actually more environmentally sound not to have a cat and hence burn less fuel - unless you still press the loud pedal the same amount and just go faster of course

My cat actually spit it's guts out and the car still passes UK emissions.

As for what VinceNoir said about UK rules - 92 if the car is listed in the EG database. If it is a JDM import it has different emissions equipment to the UK car and although the majority of MOT stations will MOT it as a UK GT you are perfectly within your rights to ask them to MOT it as a JDM SS-II up to August 95 - the SS-II won't be listed and so they only have to do a pre cat test which any celica not passing is in serious trouble given that my 1969 beetle passes it

My JDM SS-II is actually a 1996 model - and it failed today on emissions - so do you think i can get away with letting them know it is not a UK GT? If not how much is a new replacement usually?
