Shelby Performance Parts Upgrades - Six Easy Pieces
Quick And Easy Shelby Performance Parts Upgrades For '05-'09 Mustangs
Shelby Cat-Back Exhausts
When Shawn laid out the Shelby Performance Exhaust system, it looked like an installation job for a professional shop. However, the procedure takes 20 minutes due to precision construction for an accurate fit. There's nothing to weld, and the pipes and mufflers fit tightly into the vacated stock location. This system yields 7 to 15 percent horsepower gains.
Shelby Map Light Insert
Another trick piece is the Shelby map light insert. It's made from stamped aluminum and has a brushed satin finish. You can purchase this trim piece with or without the Shelby logo.
