How much would it cost to get dual exhaust?

How much would it cost to get dual exhaust put in my 2006 3.5 L Dodge Charger?

• also what would this do to the performance and the mileage of my car?

• Answer:

  Depends on if you want a cat back system or true duals, exhaust on a V6 usually sounds like crap, but it can be done. I would say anywhere between $300-$700 depending on what you want done. Performance wise, it would help a little, but not too much, maybe 5-10 HP at the wheels. You need to get headers, a bigger Y-pipe(this is one of the most restrictive parts of your exhaust), a high flow catalytic converter(that is if you live in a state where they do the sniff test, if not go without the cat if you can, some exhaust shops might not allow this though), and performance mufflers to get the best benefit. Try looking up some forums for your vehicle like dodgetalk.com and look in your specific vehicle forum for the best help from people who have done this mod.
