Increases Horsepower and Torque. Do you already have a Cobb 3" Cat-Back Exhaust installed on your EcoBoost Mustang? If so, convert your turbocharged monster to a full 3" exhaust by upgrading to a Cobb 3" Catted Down Pipe. By increasing the size of the down pipe and replacing the restrictive stock catalytic converter with a high flow version you will see an impressive gain in both horsepower and torque. This Down Pipe was designed for those Mustang owners who are upgrading their EcoBoost in stages as their budget allows.

Aggressive Throaty Sound. Cobb's Down Pipe will not only increase the horse power and torque of your EcoBoost Mustang, but it will also increase your Pony's sound as well. This Down Pipe will add a much more aggressive and throaty exhaust note to the sound of your turbocharged Mustang, when compared to the factory down pipe. When combined with Cobb's 3" Cat-Back this complete system will really wake things up.

High Quality Construction. Cobb manufactures their Down Pipe from high quality T304 stainless steel for superior strength and long lasting corrosion resistance. With 3" diameter, smooth mandrel bent tubing, this Down Pipe features a 200 cell count metal spun catalytic converter for optimal exhaust flow. Cobb's Downpipe also features two standard O2 fittings for use with the factory upstream and downstream O2 sensors.

Calibration Required. Installation of this Cobb Down Pipe will require the use of a Handheld Tuner to reprogram the vehicles computer (ECU) for operation. By reprogramming your Mustangs ECU you will be able to realize the full power potential that this Down Pipe has to offer.

Application. This Cobb 3" Catted Down Pipe is specifically designed to fit the 2015-2017 EcoBoost Mustangs equipped with the turbocharged 2.3L in-line 4-cylinder engine. This Down Pipe will require the use of a Cobb 3" Cat-Back Exhaust part# 5M2100 for proper installation - see option above.

    Best sound and Gains

    I bought this down pipe to make my car louder and to add horsepower and torque and I am not dissatisfied! This makes a huge noticeable difference in sound and power. If you are looking to make your ecoboost sound better I would recommend this down pipe.
