They tell me that all cats after the downpipe are off and that the downpipe cat is a high flow.

So the middle section now has a resonator as does the small front pipe before the downpipes, is this correct ? or are they also high flow cats?

Help please

The wealth of knowledge on here i thought you would be tripping over one another to tell me

Anyone ?

Where all the brains when you need an answer?

The brains have all gone away to translate your question into english I'm afraid.

As a non-brained person, I have had an educated guess at what you may be on about.

It might help if you tell us which age of car you are talking about to start with, but here goes:

For newage UK cars:

WRX - up-pipe catted/ downpipe catted/mid-section catted plus has resonator. None are "high flow" cats.
STi - up-pipe non-catted/ downpipe catted/ mid-section catted plus has resonator. None are "high-flow cats.

When PPP is fitted:

WRX PPP- up-pipe catted/ down-pipe catted/ mid-section de-catted plus has resonator. None are "high-flow" cats.
STi PPP - up-pipe non catted/ down-pipe HIGH FLOW SPORTS CAT/ mis-section dec-catted plus has rersonator.

The mid section is made of two parts BTW.

For classic cars, no cats are removed for PPP.
