This is the question I wanted to ask a while back since the exhaust systems on GTI337, 20th AE GTI and GLIs are made from stainless steal.
Since it has been now 18 years when GTI337 was released first and 20th AE with Jetta GLI followed after I am curious how long your OEM car exhaust system lasted before needing replacement?
I have 90k miles on GTI337 and suspect first thing needing fixing will be a catalytic converter before anything else on the whole exhaust system. Time will well if that is true.
Please share your experience.
