Hey guys I just purchased a 2013 c350 4 matic I'm looking for a little more hp does any one have any ideals and for a mid price range I'm open to all options and and one more question what's the cheapest way to to make it a bit louder?

 

With any car, cheapest and easiest place to start with are the air intake system and exhaust system.

Stock air intakes are very good so put the cash elsewhere like toward an ECU tune.

 

Yup, tune is the way to go.
