2011 Ford Mustang GT Intake And Exhaust Installation - Inhale And Exhale - Tech

The Stainless Works headers go in easier than the stock pieces come out.

Lamotta reconnects the steering shaft.

Lamotta then transfers the O2 sensors to the new components. One of the stock wiring harness ties must be removed at the top of the transmission so that all of the pigtails will reach.

The catalytic converters slip-fit onto the headers and are fastened with the provided clamps.

The lead tubes attach to the cat-back system with the stock clamps. They can be removed using a small pry bar (or flat-head screwdriver).

Gagliardi and Lamotta then install...

...all of the components,

...but they don't tighten anything at this time.

With the X supported, Lamotta then tightens all of the clamps.

The finished system fits nicely and looks even better.

In stock form, the '11 GT made 371 rwhp and 363 lb-ft of torque.

With the C&L Performance cold-air kit and tune, it made 397 rwhp and 380 lb-ft of torque, a 26hp and 17-lb-ft improvement. With the addition of the exhaust, it made 419 rwhp and 384 lb-ft of torque, a 48hp and 21-lb-ft improvement over stock.
