attilauk Posted March 14, 2005 Share Posted March 14, 2005 is there anyone on here using a High flow cat setup? with the advances in technology being made im sure a high flow setup could provide the same benefits of a total de-cat whilst still passing emmisions regulations. the reason i am asking is i noticed MVP have a high flow cat setup on their website at what looks like a very good price and i wondered if anyone had any experience of them.

Scoboblio Posted March 14, 2005 Share Posted March 14, 2005 Can't help with the question mate, but I'd be interested in knowing this too Back in my mondeo days there were a few guys who managed to 'gut' their cats so they looked standard from the outside but contained nothing restrictive.... would be a definate advantage from and insurance perspective. Wouldn't help with emmisions though. Quote Link to comment Share on other sites More sharing options...
HunterJ Posted March 7, 2006 Share Posted March 7, 2006 Anyone clued up on this? I was thinking about decat on the back and a high flow on the front... Would this still need a restrictor ring on a J-Spec? Cheers Jamie Quote Link to comment Share on other sites More sharing options...
jason m Posted March 7, 2006 Share Posted March 7, 2006 I think you would be better off putting it in the second cat position, as the first one is only necessary when the car first starts. As I understand it the car will pass emissions with the second cat as long as it is warm. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 7, 2006 Share Posted March 7, 2006 Why bother, over a year you will spend more time putting fuel in than you will changing the 2nd cat pipe back to an OE cat, and back again... Quote Link to comment Share on other sites More sharing options...
