Quiet exhaust system for 454 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Currently waiting on powder coating for my wheels to finish up my wheel/tire project. While I am waiting, moving on to the next project.

The truck currently has a 7.4L 454 with long tube headers and Flowmasters. They exit right under the rear seats and the exhaust does not extend to the back unfortunately. The exhaust is WAY too loud for a daily driver for me and I will be changing it.

I am going back to stock exhaust manifolds and have been looking at the Flowmaster 70 Series vs. Flowmaster 50 Series Big Block mufflers. Has anyone had any experience with either of these?
