Improve sound and performance on your 2015+ Shelby GT350 & GT350R with this Redline catback from Stainless Works. We?ve engineered a drone free aggressive muffler tuned specifically for this improved coyote engine from Ford. Featuring the latest in active exhaust technology, our in-house engineered valve bolts directly to the factory electronics to allow for all exhaust modes. From the closed valve ?Quiet? mode, to the chambered ?Normal? mode and to the wide open straight through design on the ?Track? mode. In addition to the tuned mufflers, we?ve also utilized 3? tubing into our H-pipe crossover for an improvement in flow over the stock exhaust. Our Redline series is designed to get the most aggressive sound out of your ride. We design Redline systems to maximize the volume and tone of the engine, while still eliminating any drone in the cabin. Resulting in a feeling that will make you want to high-five your friends in the face. This system utilizes your OEM tips. Designed to fit to the performance connection point.
