I plan on buying Flowmaster 40 series and bringing my car and the flows to my local mechanic whos pretty friendly with my dad, and asking for true duals. Now, does this make sense? I don't want to sound like an idiot when I speak to him. My main question though is how much does this typically cost for the exhaust + labor? Thanks

 

Mine cost 350 with 2 flowmasters, 2.5" piping and chrome tips.
