2011 Ford Mustang GT Zex Blackout Kit - Feed For Speed

The flanges on BBK's short-tubes (PN 16320, $449.99) are cut from super-thick, 3/8-inch mild steel. To help make the difficult install task a little easier, BBK adds bolt slots (instead of holes) in various places on each header.

Here's an OEM/BBK header comparison for you. The factory's stainless-steel tubes (right) are configured in a tri-Y short-tube design, which is markedly different (shorter overall tube length) from the four-into-one-tube setup of BBK's 5.0 headers.

BBK's 23/4-inch, X-shaped crossover (PN 1460, $169.99) is a direct bolt-in replacement for the OEM H-style exhaust pipe. The headers and X-shape crossover were the only exhaust mods that were done for this project. Catalytic converters and factory mufflers were both reinstalled.

As you would expect, the replacement headers are a tight fit against the Coyote engine. This shot is offered to give you a look at the nice polished-ceramic coating that's available. BBK also offers its short-tubes in chrome and stainless steel.

When installing the X-shaped crossover, the OEM barrel clamps are used to connect the new tubing to the exhaust. Jesse uses a cutoff wheel to zip the clamps free of the stock pipe.

While the Blackout nitrous system shown here is new for '11 Mustang GTs, Zex's Nitrous Management Unit technology has been around for quite some time...
