V2 Cat-Back Exhaust System

2015–2023 Ford Mustang EcoBoost · 3″ 304 stainless, dual 2.5″
Does NOT fit convertible Mustangs, Mustang HPP, or Mustangs with Active Exhaust.

Overview

The COBB Ford Mustang EcoBoost Cat-Back Exhaust System directly replaces the factory exhaust. It includes a 2.5″ adapter that tapers down to work with the factory downpipe — or run it without the adapter and bolt straight to the COBB 3″ downpipe.

The system runs 3″ from the downpipe, then splits into two 2.5″ sections feeding a COBB-stamped muffler. Engine rumble and turbo noise are amplified but kept in check by the 10″ resonator. From the rear, dual-walled 4″ tips with the COBB logo finish the look.

The V2 Cat-Back’s 3″-to-dual-2.5″ configuration delivers a more subtle, refined tone than the original 3″-to-dual-3″ design. It is a direct factory replacement — no tuning required.

FFP knows the EcoBoost Mustang.

— Why FFP stocks COBB

COBB is the standard for EcoBoost Mustang performance.

The S550 EcoBoost responds hard to the right parts — and COBB has spent more time on this platform than anyone. From the Accessport ecosystem to bolt-on intakes, exhaust, and suspension, it is proven, repeatable hardware. That is why we stock it.

Want the work done by techs who build EcoBoost Mustangs every week? Drop the car in Thousand Oaks. Prefer to install it yourself? Every COBB part ships with clear instructions and direct-fit hardware.
