Ive decided im getting a Hooker Aerochamber muffler. But compared to my stock exhaust setup, what size muffler inlet/outlet should i get? And yes i know it looks terrible, but it was on there when i bought the truck. I dont even know what kind it is. And it sounded good the way it is until it something inside it started rattling.
Incase you cant read the numbers on the picture, thats 2 3/4 in and 3 in.
