I'm a new 1.6TD owner

i wouldn't bother with a larger exhaust without a larger downpipe to match, but thats my opinion. with that engine, 2.5" seems to do well, thats what i have on my 1.6TD and 1.9TD. passenger performance is now offering 3" dia downpipes which should reduce EGTs even more than 2.5". only real issue then is fitting a 3" exhaust without hitting the rear beam, etc.

2.5 or 3 inch exhaust will do the job nicely.. but definitely get the down pipe.

I spoke to the kind folks at Passenger Performance today.  I'll def be going with a 3 inch downpipe and 3 inch exhaust all the way back with no muffler or resonators.
