Hi,
My mom still has her mk3 saloon polo. She just put a new clutch in it and it runs sweet as a nut. However, the exhaust system is feeling a bit in need of repair. It has multiple leaks in it. I'm concerned that the cat may have started to corrode away now, given its 1990 birth date. Its an AAU engine, and I was wondering if one could fit a decated downpipe, since the car is pre 1992. This should make it go better too. Any ideas where I can get one?
