Improve Exhaust Flow, Lower EGTs

Whether you're looking to keep EGTs in check while you stack on modifications or you need a new custom exhaust note for your 2015-2016 Super Duty, the Diamond Eye 4" DPF-Back Single-Exit Exhaust System gets the job done at a price point that's hard to resist. The 4" aluminized tubing will provide a far more substantial exhaust flow than your stock system, resulting in lower EGTs, improved performance and a bold exhaust note. The system is capped off with a 5" vented stainless steel tip for classic performance styling. This Diamond Eye 4" DPF-Back Kit features a single-exit design that exits in the factory location for a clean, near-OE look, while its larger tubing and specially-designed muffler improved flow for a nice boost in power and fuel economy.

Premium Construction Without the Premium Price Tag

Everything you'll need to get the kit installed properly and as quickly as possible is included, as well as in-depth installation instructions.
