i think its 2.5, go outside and measure it would be your best bet, sometimes its bettter to have a CAT in as you can loose peformance, your best talking to him mate, he no's his stuff, he has done all sorts of Stainless steel fabrication for me

thank,
but i'm from israel

thats why i want to order from ebay..
i read about that in other fourm (i didn't find info on this here) and i told that if the stock cat is not blocked that i won't fell any diffrence..
is that right?

the exhaust system on the polo is very restrictive, i had one fitted to mine, a full system, everything except the manifold, i had a stainless peformance cat in and i got a read out on the rolling road of a gain of 7.5bhp

wow 7.5 it's alot!
i would like to get this increase of power
what do you mean by saying full exhaust system??

i allready have this backbox fitted to my 6n2

but i tell you the truth i didn't fell any diffrence in accelleration

This was on my 1.0 6n2 that i gained the 7.5bhp it was everything except the manifold, you wont gain anything from just a back box, probably lose power if anything

7.5 bhp on 1.0l engine thats a huge diffrence.
