The standard cat wont restict a K04 turbo but will restrict a bigger turbo. It's the downpipe thats restrictive.

Mines a K04 hybrid but i doubt the small size increase would make much difference on the cat level. I'd heard the downpipe was the problem and not the cat.
i wasnt sure about goin hybrid.ive herd alot of diffrent things.how much bhp can the hybrid really give you with the following things that i have already done.or which big turbo do i go for
one of the chaps on here tested the CAT and then replaced and the difference was virtually none existant and he was running massive boost on the KO4...that was an RR test done on the same day same conditions etc etc
could i get 300bhp out of a hybrid with my 3inch downpipe and decat.ive fiited the 3ich downpipe and decat so will i need to fit a powerflex dogbone bush
how do u meen about the power.shud i have got the 120cell cat insted of the decat or do u meen i shudnt of botherd changing the downpipe an cat at all
Change the Downpipe, as its the most restrictive in the Exhaust route, What the other guys are saying is DE-Catt'ing your car is not worth it,
I have sports CATT's and i do no not think there worth the money, If you wanna change them or make the route less restrictive DE CATT it, 1Animal1 says someone has actually tested the flow or something of the CATT and found virtually no difference....
I know that current Uk emission laws are fairly stringent and that CATT's must do that job somehow.... Seems strange that they manage to do it with non restrictive fairy dust

fair comment tankie but take your argument to the chap that RR'd his car @ star performance, fitted a sports CAT and then RR'd it again same day with virtually no if not no gains at all.... regardless that is one of the main reasons people simply dont decat or sports cat their S3's..... take it or leave it but unless you prove otherwise

DP is restrictive, but it would appear difficult to get one without replacing the cat at the same time. I've been looking, but can't seem to find any off the shelf options as all the 3" DPs seem to need to be partnered with a single cat (from the same supplier!) rather than the OEM twin set up.
