Just tossing around the idea of installing my factory '12 Dodge Challenger cat back system on my '14 300C w/5.7 hemi to perk up the exhaust note a bit and keeping it factory at the same time. Only differences I see are longer wheelbase length necessitating a couple of extensions for the front of the system to connect to the factory mid pipes. System is still like new hanging in my garage since 2012 when I installed a Flowmaster cat back on the Challenger.
Only expense would be a couple sections of 2.5" ID/OD pipe from the local auto parts store, already have clamps, etc.
Any ideas/advice?
