Milltek high flow cat

[stevecupra]

Hi,
Does anyone know how much difference a high flow cat will make to the performace of my car power and volume wise? It is a Revo`d 20vt with a Milltek cat back system.

Yep it will make a difference, throttle responce will be better, exhaust note will be better and it should make it slightly quicker.

made big difference on my 20vt and boosted 2 psi more with revo stage one

600cells to 200 cells will free up the turbo to give you quicker spool etc

Are these sports cats still ok come MOT time?.

Wont it be even more beneficial to then upgrade to the Revo Stg 2 after fitting the uprated exhaust?

Should be! Even a 100 cell CAT should pass MOT ok!

what's these Cells you talk about?

is it like the filtration rate. i.e. std oem filters more like 600 Cels and sports is like 200 Cels?

See my reply to your "sports cat" thread for details. 200-cell is sloppy shorthand for 200 cells per square inch (in the catalyst's honeycomb construction), much less than the factory-fitted cat (which have maybe 500) so each cell is a bigger bore.

I've never come across that term before, the only use of cel I know of is in hand-drawn animation. But in general terms, a catalytic converter is not a filter, so filtration terms are not useful in characterising it.

ok, was thinking of going to revo stage 2 after having the 4 bar fpr done as well. Anyone any idea on cost for the cat and the fpr?
