exhaust differences?

[digby130?]

hey guys,
im looking for a new exhaust for my 05 ibi 130FR (1.9tdi)
but my main problem is that i dont know the differences between the types!
from a quick search milltek are the best
if i someone could give us a hand with these questions/parts i would appreciate it!:

non-resonated means it sounds more like a petrol? is that right?

large bore downpipe?

hi flow sports cat and downpipe?

cat back?


i think the downpipe means it will be larger, and is the part from the engine to the catalyct converter?

and cat back is the part from the catalyct converter to the tail pipes?
probably got that completely wrong!! help !

non resonated sounds like a petrol and resonated is not as loud

large bore is 2.5" on the downpipe, larger than stock downpipe giving some gains

sports cat is used on a petrol, as they need a cat to pass an mot, a sports cat is not as restrictive as a standard cat, but the car still passes the mot with a sports cat

cat back is basically a system from the cat back to the tailpipes, hence "cat back"

hope this helps mate
