Hello I ave got a 2013 ford Taurus SEL AWD with the 3.5l v6 naturally aspirated. I was wondering what I can do in terms of exhaust? The stock is just to quiet but I dot want a screaming raspy exhaust. Also I would like to try and get mufflers welded in instead of a 1200+ dollar cat back exhaust. I'm gonna do a CAI eventually too but winters coming so mods are slow. Another thing is a tune. Once I have my exhaust and intake settled what kind of tune can I get into a 2013 Taurus with a 3.5l? Is a tune even worth it? I mean the main thing for me is I would like more responsive throttle and less dragged out shifts but I don't know if that's possible to change. The car does have 96,380 miles so I'm not sure I'll be doing a tune to wot accelerate all the time and get a top speed. To much wear. Lol Also how does the AWD work on these Taurus's? Is it rear wheel or front wheel drive and then when traction is lost computer transfers torque to all wheels or alternates wheels to get traction? Just curious I know its not 50\50 transfer to front and rear constant that would strain the drivetrain to much.
