Catalytic converters

[harry henderson]

I could do with some advice on the differences between catalytic converters. My car is ready for a new set but the difference in price from the cheapest to the most expensive is pretty vast. They start at 70 and go up to 400.
So has anyone got any advice on which ones to get? Cheers.

Would the 400cpsi cats be ok for a 4.2 then? I ask because the ones at Racetech are described as high flow 400 cpsi and the ones at Tvrparts don't say what they are rated at.

The 400 cats aren't that cheap, they are on offer at 255 plus vat and p&p each. That's why I just assumed they would be ok. Glad I didn't just buy them straight away.

Has anyone got an original 4.2 200 cpsi cat they want to sell?

That could definitely be an option. I managed to get 1 unused original cat so if I could find another that would be great. Cheers for the link.
