okay let me say a few things. I have a 1.8 and Im about to get under it to work on the exhaust.
the gti6 has a 4 branch equal length manifold which is long then has a short cat (1 lamda) and then standard centre and backbox.
the 1.8 has a log style crap manifold with a long cat (1 lamda) and then standard centre and backbox.
GTI6 MANI-------><CAT---->< ---- CENTRE ---- > < BACK BOX >
XS MANI -><CAT----------- >< ---- CENTRE ---- > < BACK BOX >
What you need to be careful with buying after market exhausts is the joins. You will find far more aftermarket gti6 exhausts than you will 1.8.
I bought a magnex but it wont fit as its sleeved and the 1.8 cat design is flanged.
On the gti6 i believe the cat is flanged and sleeved allowing after market exhausts to fit.
As for sounds.... I run my 1.8 with a decat, decentre pipe and a standard backbox. Its really raspy, not too loud, not too quiet and with my mapping makes for epic pops and bangs.
Now that I have fitted the magnex which is a larger diameter its boomy between 1 - 2.5k and then is quiet for the rest of the range.
hope that helps!
