    Add Horsepower. Free up the restrictive stock exhaust system on your Shelby GT500 and enjoy more horsepower with a Magnaflow Street Cat-Back. By reducing back pressure and giving your Supercharged Mustang a free-flowing exhaust, you'll see great horsepower and torque gains.

    Classic V8 Muscle Car Sound. The Magnaflow Cat-Back Exhaust System includes a set of two Street Series Mufflers that feature a free-flowing, straight-through perforated stainless steel core, with stainless mesh wrap and acoustical fiber fill to deliver that smooth, deep muscle car tone.

    Quality Magnaflow Construction. The Magnaflow Street Cat-Back system is constructed from mandrel bent 3" stainless steel tubing for long life and a perfect fit. The system features two Street Series mufflers that end with black finished stainless steel 4" quad tips, that exit in the stock location for impressive good looks.

    Application. Made to be a direct bolt on, this Magnaflow Street catback will bolt straight up to the factory Mid-Pipe without any extra modifications required on your 2013-2014 Shelby GT500 Mustangs for a deeper classic V8 sound.

        Do you have to change the valance or any other stock GT items with the quad tips? Or can I put it on just like a 4" in double tip?

        • Hi, This Magnaflow Street Cat-Back Exhaust w/ Black Quad Tips is a a direct bolton for the 13-14 GT500s and will bolt straight up to the factory Mid-Pipe without any extra modifications required. if you plan on using this cat-back on a GT it will not bolt up to a Midpipe for a GT.

            Good exhaust to relive hp robbing back pressure

            Looks amazing, sounds amazing. Frees up a lot more airflow then I thought it would. A must if you have changed the air intake or swapped pullies. Why a four and not a 5, you almost need ear plugs when driving, very loud inside cabin.

            Magnaflow Street quad exhaust

            This exhaust system is awesome has a nice rumble at idle and really growly when you get on it past 4k rpm and even past that there still isn't any drone in the cabin. Gives it that real aggressive GT500 look. Real easy install long as you use a lift took less then a hour.
