This MBRP exhaust system is great for car enthusiasts who want to upgrade their 2015 - 2016 Dodge Charger or Chrysler 300 on a budget. Whether you're driving on the highway or showing off at a car meet, it'll give your vehicle a great sound. It uses heavy - gauge aluminized steel tubing which is a good fit for dry climates with less precipitation. The mandrel - bent tubing helps in getting more power from your engine.
