Decide I like the whole dual exhaust on the Focus so I went along and did it myself:
Parts I used all bought online at rockauto.com
Walker Muffler 22253 $56
Walker tailpipe 43831. $8
Walker tailpipe 43846 $8
3a oval tips. $30
I still need to refine the tips and the cut out in the lower bumper. I'm thinking of a slight flare on the top where the tip comes out to mimic a "factory" look.
Also did a change of the A/C knobs which I reallyl feel finishes off the interior.
