Most would agree that the Dodge Challenger SRT is not only one the coolest-looking cars produced in the past decade but doesn’t sound too shabby either. So when Mopac Auto Supply in Langley gave us call to let us know they were doing an exhaust upgrade on this retro rod we couldn’t get there fast enough.

Before I continue, I want to take a step back and mention that if anybody out there has any tips that we missed that have helped them out when doing the same things, don’t hesitate to let me know and I will pass them on during this series.

We did a complete sound deadening installation in our shop demo vehicle. Using all of the various products from Dynamat and a few other products, this 1983 Buick Regal is quieter inside then any Lexus or Mercedes-Benz.
