I've received a lot of questions is relation to the Charger's cam and exhaust. Not a great surprise, as together they provide such a wonderful note.
The cam specs are: 527 lift & 242 @ 50
I have provided some photos of the exhaust. All our custom exhausts are fabricated in-house...one of Ol' School Garage's specialities. The twin 2 1/2" pipes run from the factory split manifold to an X-pipe and than through a pair of Flowmaster mufflers. The pipes have been coated in-house with HPC coating.
Hope this helps.
