The 2016 Ford Shelby GT350 Mustang and it’s R-badged cousin are undeniably great-sounding cars, thanks to their shared 5.2-liter, flat-plane crank V8.
But of course, what’s great can still be made better, and to that end, Stainless Works has come up with a replacement exhaust header system for the venerable Shelby GT350 that unleashes even more of the engine’s fearsome yowl. The company has put together a little video, embedded above, for maybe-buyers to hear the new system next to the factory one while the car starts up, revs, and accelerates, both in “Standard” and in “Track” mode.
As implied by a name like “Stainless Works,” these headers are formed of TIG-welded, 304 stainless steel. The company had Big Three Racing test a Shelby GT350 equipped with its USA-made stainless headers and found that, in-conjunction with a cold-air intake and a software tune, the super-pony’s 5.2-liter V8 put down an extra 25 horsepower at its peak, with some regions of the RPM range showing a 30 horsepower improvement.
Be sure to catch the crisp, boisterous sound and fury of Stainless Works’ new Shelby GT350 headers in the video above.
