Best High flow cat?
 

Hello I'm get the car remapped soon (MY01 WRX). I have a centre decat and BB and would like to change the downpipe and up pipe. But i want to retain some sort of cat. Does anybody have any experinaces with high flow cats. I know that TSl and power enginering have one.
Any ideas please

Peter

Hi peter

As you seen this Thread

Hayward and scott will make one to your requirements for about £450+vat. they useautocats

Follow andy97's link to that thread Peter, i am only replying to vouch for the TSL sports downpipe, as i have one on my MY03.

Peter,
keep an eye on ebay mate, there's a guy on there who seems to be able to get the d/p that's used on the sti ppp, the one with a high flow cat!! direct replacment for yours, and lots cheaper than any of the other options!!

I second the comments about Prodrive downpipe, one of the best cated downpipes for medium modded Imprezas.
