In addition, long-tube headers aren’t already better than shorties unless you’re going to all-out racing and high-RPM operation. ![]() Header selection affects performance more than anything else. Not all X-pipes improve performance and sound. Not all performance cats are performance cats. When you’re shopping catalytic converters look at flow/restriction. It is more the headers and mid-pipes that yield performance gains. Are you doing it for sound, performance, or both? Most mufflers, regardless of what manufacturers tell you, are engineered more for sound than performance. While you are shopping, check local smog laws to make sure these exhaust system mods are legal for your area.Īs you shop exhaust systems think about why you are upgrading your exhaust system. Roush Performance is another good source for Coyote exhaust systems, with everything from headers to mufflers, which improve high-end horsepower primarily. Get a pro tune immediately after changing the exhaust system. Keep in mind that most long-tube headers and aftermarket mid-pipes require custom tuning to get their full power gains and avoid engine damage. Stage 3 also has high-performance headers and performance mid-pipes, which can yield a nice throat. All Mustang exhaust systems come from top-quality manufacturers such as Magnaflow, Flowmaster, JBA Exhaust, Bassani, and Borla, and can give your Mustang additional horsepower and torque. From a raspy race car sound to a deep and throaty muscle growl, these folks appear to have it covered. When it comes to achieving the sound that’s right for you Stage 3 Motorsports offers a nice selection of mufflers and systems. Stage 3 Motorsports puts a nice system together for the 2011–2016 Mustang. Borla mufflers have always been the industry “loud” in all their many forms. Atak is downright loud and snarly, a straight-through muffler void of restriction. S-Type gets a little louder with less restriction. Touring offers a soft throat, which is good for cruising. ![]() Chrome tends to rust with time and use, which makes it one of the least recommended choices.īorla offers at least three muffler types for Coyote Mustangs and F-150s: Touring, S-Type, and Atak. Ideally, you choose stainless or a ceramic-coated header. Any header you select for a street Coyote should be SMOG legal where you live. This enables the system to keep an eye on catalytic converter and engine function.Īlthough long-tube headers are time-proven in terms of power, they aren’t always recommended for street applications. One O2 sensor is ahead of the cat while the other is in the cat. The end result is low-restriction single-stage cats with two O2 sensors. Ford engineers looked at every aspect of the Coyote’s exhaust system. In Chapter 12 I test three header types on a 2011–2014 Ford Performance Racing Parts crate engine and give you the results.Ĭatalytic converters were once considered stifling to performance, but not anymore. Your challenge is to determine which ones yield the greatest benefit for your Coyote. However, BBK, JBA, Ford Performance Racing Parts, and a host of others produce short- and long-tube headers for the Coyote. It is challenging to beat Ford’s factory Coyote headers. ![]() It begins with a great aftermarket exhaust system if you’re seeking an easy upgrade. Torque should be your priority on the street.Īlthough Ford’s best engineers did an incredible job of exhaust system refinement there’s always room for improvement. Enthusiasts always want more horsepower, but torque is what gets your mojo on. Torque is another story and a huge challenge for engineers and product planners. Bean counters didn’t want them because they’re twice as costly to produce as cast-iron exhaust manifolds, yet crucial to emissions, power, and fuel economy.īecause the Coyote’s factory shorty header is unique with its equal-length style, it has enabled the Ti-VCT to produce some 400 ft-lbs of torque. These guys had to fight for them because it was everything to closing the power gap. The Coyote has short tri-Y headers that were painstakingly thought out and executed by Ford engineers.

Headers might not seem like much of a big deal in the big performance picture, but exhaust scavenging is important and was a great area of focus for Team Coyote. The Coyote’s exhaust system is just as critical to power and efficiency as the rest of the engine and driveline package.
