Stainless Works GT350CBXFCR Redline Cat-Back Exhaust System with X-Pipe & NPP Valve

Transform the sound and performance of your 2015+ Ford Shelby GT350 or GT350R with the Stainless Works Redline cat-back exhaust system. This complete system features a drone-free aggressive muffler specifically engineered for the Voodoo flat-plane crank V8, delivering maximum volume and tone without cabin drone.

Active Exhaust Technology:

The system includes Stainless Works' in-house engineered NPP (Noise Production Performance) valve that connects directly to factory electronics, enabling full control of all OEM exhaust modes. Switch from Quiet mode with the valve closed, to Normal mode with chambered sound, to Track mode with wide-open straight-through flow for an aggressive race-inspired tone.

Performance X-Pipe Design:

Features 3-inch mandrel-bent tubing flowing into a true X-pipe crossover configuration that significantly improves exhaust flow over the restrictive factory system. The X-pipe design balances exhaust pulses between cylinder banks for optimal scavenging and a distinctive aggressive exhaust note.
