I am wanting to give my 2010 Ford Fusion Sport a little more kick and i was going to start with the exhaust. The engine is a 3.5L V6. What exhaust set up would be most binificial?
Don't expect much out of a V6. A cold air intake & K & N air filter will help some. Tube headers too. A larger dia. pipe cat back exhaust is a must for "tuner" cars. I once had a Camaro with chambered exhaust. The whole exhaust pipe was crimped with baffles inside too. It was loud & sounded great because no mufflers were needed. Walker used to make chambered exhaust check around online.
As far as exhaust, I would go with a new set of headers, and muffler for the sound, as far as power, the headers would get you anywhere from 15-35 hp depending on the brand and etc. For the engine, to start I would do CAI, Pulley, Spark plugs. Extra things u could do is maybe a set of performance tires, and maybe even coilovers.
