How much roughly

[S40kieran]

How much would I be looking at roughly to have a stainless steel cat back exhaust fitted to my d5. And are power flow any good.

Different car but I've just had one done on my Subaru - 490 quid from Long life, for double system from 3rd (!) cat back. So that should be a maximum price for fab work. Mind you down south that might be pocket money I don't know

Does it need it, they do seem to last a very long time .
I guess you will want to remove a box little bit more noise.
Down here there's a couple of choices but to be fair any exhaust made of stainless and a bit bigger dia is going to help, but not sure of the numbers you might get .
