Description

Plan on a 1-5 week wait for these systems. Refunds will not be given if you can’t wait.

Choose the configuration that best meets your needs.

The year 2015 is a split year, with the 2011-2015 downpipe secured to the turbo-direct pipe using a V-band style clamp. The 2015.5-2016 model, on the other hand, uses a 3-bolt flange style connection. Be sure to visually verify the style of clamp your truck is equipped with.

Important Reminder: To ensure smooth operation and prevent check engine lights (CELs) or dash warnings, this exhaust system requires compatible tuning. For optimal performance and seamless integration, we recommend pairing it with the EFI Live AutoCal V3 tuner.

the power is noticeably better, and the throttle response is much quicker. It’s like I’m driving a different truck
