69 A56 340 'Cuda 4 speed

Curt, I agree that in this case, I'd seriously consider using one of the companies that sells systems made for your car, like the ones Tom Swope sells at Accurate. You do not want people welding hangers on and welding systems
together with mufflers that drone and drive you crazy. My opinion coming out here but I know what 340s do and how they drone and resonate with the wrong mufflers and hangers.
Please holler at me if you want some more behind the scenes testing info.
No matter what you do, keep sharing all the cool stories! :)
