This 2011 Dodge Challenger SRT8 came in looking for more power and a meaner sound. Before we got started on this project, a baseline dyno was performed to see the before and after off these upgrades. We installed a full Stainless Works exhaust kit which includes headers and mid section pipes and paired it with a set of Flowmaster mufflers and beautifully polished tips. Finally, a Blackdog custom tune and dyno. The end result? Better exhaust efficiency and a thunderous rumbling hemi cut loose on the streets. Check out the gains!
