Here in Ohio i have emissions testing, I dont know about in the UK but we have the actually emissions test and a visual inspection. I run the Magnaflow High Flow cats
and they seem to work quite well and they really are not that expensive, I have yet to fail any of my emission tests with them on.

I believe the part number of the cats is 59959.

Wow, thanks for all the responses.

It's good to see you guys think I can probably pass our emissions test, I hope I will.

Keep it in the 224 range with a high(114 or higher) and you should pass, but if you go with a big cam your probably out of luck.
Thanks for the pointer.
My cam probably wont be untill 2010 (Still time to find out more about it!), but I have herd I may have to be cautions with the size of a cam regarding emissions, thanks for the tip.

For sure get some Magnaflow Metallic cats minimum.
You say 'minimum'. Is there something else I can do to help?
I already see a good tune will help me out, as keeping AIR might help.


So Magnaflow cats (x2), part number 59959, is now on the 'to buy' list.

If anyone has more to add, please post up.

With regards to keeping the AIR system, aparently the car has to warm up before the emission test is carried out.
I believe the AIR system helps the cats to reach operating temp quickly, so I guess I can deleate the AIR system and still pass?

Are You using 3" Piping on your car? That cat is for 3" Pipe (59959). We also have a 59956 which is a 2.5" Metallic Cat.

Note that if you purchase them, you will have to either construct your own y-pipe as a custom application or buy a y-pipe without cats and weld them in. Most catted y-pipes give you crappy cats. I had a custom y-pipe made with those cats specifically because they're so good.
Ditto, these are very good flowing cats...
