Im running my own custom single/dual system. Cut it behind the factory 2 bolt flange, ran a 3" mid pipe to a turbo muffler (keeps out the drone), then 2 2 1/2" tailpipes kicking 4 inch rolled tips behind the tires. Soon ill be ordering a set of Direct bolt on JBA'S and cutting in some magnaflow High flow converters.
Always get your exhaust done by a local professional shop. Its usually half the money and all you have to do is sit down in the office and relax. Well worth the money. I could never pay for a pre bent online exhaust. Most of the time they never fit, once the dies get worn out over time you end up being 5 degress off here and there and by the time you get to the back its 20 degrees off. If anyone here is in Mass and needs exhaust work done message me. Im out in the Worcester area. Ill quote anything you need or if you have questions.
