Hello! I need some help please ASAP! My name is Beckie and I live in Vermont but am from Mass. I have a 2000 Golf that my son gave me 2 years ago and I love it, even with 257,000 miles on it. I've put about $3,000 into it so far but now I have a repair needed that I could use some help with. My nephew had cut a hole into the front pipe before the Cat and also into the Cat so I need to find which part is correct for my car. I'm seeing 6-bolt flanges and 4-bolt also. I see that the 6-bolt covers the 2 pipes which go into 1, down to the Cat, which is what I've seen when looking down behind the engine. Does anyone know if there is a specific name to this pipe with Cat included? I'd like to purchase it asap and get it fixed so it doesn't wake up the town every time I drive it. Thanks so much!
