2016 Challenger factory exhaust. 2 3/4" pipe from manual transmission. The automatics run 2 1/2". Will fit an automatic but will need adapter on your car up to the 2 3/4". Better breathing for your V8. You can replace the suitcase resonators on the back with glass packs/straight pipe for better sound and flow then bolt it on yours. All for way less than a $1600 aftermarket exhaust.
$200
