2011-2014 F150 EcoBoost Single-Exit Cat-Back Kit Sound Clips

Single-Exit kits may have a stock-style look to them (at least on the systems that don't come with an incredibly massive exhaust tip), but their levels of sound both inside and outside of your EcoBoost can differ dramatically kit-to-kit. The biggest cause of the difference is the design of the kit. More aggressive-sounding systems delete your EcoBoost's factory resonator to produce a louder and throatier sound. Less aggressive kits install after the resonator and tend to be a little more mellow, but have less cabin noise and drone. Either way, you can get a high-quality kit from us here at Stage 3, and we've even tested a few different systems on our very own 2011 F150 EcoBoost Project Truck. Check out our videos below of the Banks Monster Exhaust and the MBRP 4" XP-Series Kits.

Stage 3 & MBPR's "EcoSleeper" Cat-Back Exhaust Kit

Whether you only want a mild sound upgrade to your truck or you ended up with an aftermarket cat-back kit on your truck that you're just not a fan of, we here at Stage 3 teamed up with our friends over at MBRP to bring you their lineup of "EcoSleeper" cat-back exhaust kits. These cat-backs use 3" diameter tubing all the way from your truck's mid-pipe to its tail pipe, and features both an MBRP muffler and resonator that results in drone-free operation with some amount of increased sound and tone over the stock cat-back. These kits are perfect if the previous owner's cat-back choice wasn't your cup of tea or if you're adding on downpipes and you're concerned about the noise level with other cat-back kits. We offer three different versions of our EcoSleeper system: a low-cost aluminized version, a higher-quality 409 stainless steel version, and a hyper-aggressive black ceramic coated version. The Black EcoSleeper made it on our very own 2012 F150 EcoBoost FX4 with fantastic results.
