Re: exhaust downpipes
As I said in my post, I can supply those sections/flanges by cutting them off a crossover I have.
Post your email in a PM if you want to discuss further.
The link was just a sample of using the internet.. The actual flange is a three hole pattern. Probably very unique to GMC V6.
