is sports cat illegal to use ?

[cliosporty]

Si heard femme some installers that from last year cars from 2001 can't be fitted with sports cat due to law changes is that bull or is correct. If so why so many companies say it will pass mots etc.. with no probs.

If it passes emissions its legal.

Even some cars fitted with decats pass MOTs

There was a change in manufacturing law for cars made after 2001. Cats have to meet a certain standard if they're sold specifically to be fitted to a post 2001 car. It's basically a way to prevent the cheap cats that fall apart after a year being sold.

Sport cats are almost always sold with a "not for road use" disclaimer

My sports cat came with my Orbisoud system - passed all MOT tests so far.

Exactly - This is all that matters at the end of the day. Even a untouched car WITH a cat can fail on emissions due to various reasons

Make sure the engine is stinking hot (i.e. fans have kicked in) and you'll have no problem with a sports cat, unless something is seriously amiss with your car.

any car from 2002 should be fitted with a type proved cat a sports cat wont be type a proved same as most cheap cats.

at the moment for an mot all the car has to do is pass an emission test some will pass with a decat. from the 1st of january there is alot of new parts being introduced into the mot and one of them is that the cat has to be fitted to pass an mot so people with decats will fail the mot test next year.


just because a car passes an mot doesn't mean its legal some thing arnt testable in an mot but e.g tinted windows but its against the law to tint the front windows limo black.

They are 200 cell (means less resistance to airflow (more cell, more restriction)).

For a very concise explanation you could go to the Cats-Direct website here http://www.cats-direct-shop.co.uk/technical-information.php A quotation from their website is here:

"How Does It Work? The catalytic converter usually consists of a honeycomb structured ceramic monolith, which is surrounded by matting. The matting holds the monolith securely in place and provides a cushion against road shock and vibration. This is all encased in a steel shell to provide further protection. Another option is a steel monolith, which is more durable. The steel monolith we supply has a texture similar to cotton wool. The catalytic converter is situated in the exhaust pipe, usually close to the manifold. This is because the catalyst needs to reach a certain temperature before it starts to operate properly, so the closer it is to the engine the quicker it reaches operating temperature. The monolith is coated with platinum, palladium and rhodium. These substances cause a chemical reaction to take place as the exhaust fumes pass through the monolith. The carbon monoxide is converted to carbon dioxide, the hydrocarbons are converted into water and carbon dioxide, and nitrous oxide is converted into nitrogen." In order to see the explanatory diagram, you really need to click on the link.

For a longer, but more chatty explanation, you could go to The Naked Scientists website here http://www.thenakedscientists.com/HTML/content/interviews/interview/569/ The explanation is too long to copy and paste here, but it is well worth clicking on as it makes entertaining reading.
