Yeah I am running IS20 with Stage 2 Unitronics. On Unitronics website they have the GTI exhaust listed at 3 inches. To your point... Not sure if the length will work being that the GSW is longer. ThanksThe MK7 GTI has a 2.5 inch (not 3) vs a 2.25 inch of the TSI models. I have a 4-door hatch TSI 1.8 IS20 with a Unitronic catted downpipe. Our downpipe kit comes with a 3 to 2.25 reducer. I had no issues with the GTI catback installation using a 3 to 2.5 reducer also from Unitronic and a new valance for the dual exhaust. But I'm not sure about the fitment on the SportWagen.
I’m sure he meant an aftermarket GTI 3”, not implying it’s 3” from the factory.The MK7 GTI has a 2.5 inch (not 3) vs a 2.25 inch of the TSI models.
