I have two questions: First, what is causing the noise in the ac plenum when
I first turn the truck on or change the AC settings? It sounds like a door opening and closing quickly, and stops after 15-30 seconds.
Second, what are the inlet and outlet sizes on the stock muffler?
1994 Silverado Z71 5.7
Thanks MT
