The COBB Cat-Back Exhaust System for the EcoBoost Mustang is a direct replacement for the factory exhaust. It comes with a 2.5″ adapter that tapers down to be used with the factory downpipe or can be used without the adapter and bolted directly to the COBB 3″ downpipe. The system is 3″ from the downpipe and splits to two 2.5″ sections that each run to a COBB stamped muffler. Engine rumble and turbo noises are amplified but still kept in check through the 10″ resonator. Aesthetics are improved from the rear of the vehicle with dual-walled 4″ tips featuring the COBB logo.
Attention: The Cat-back does not fit convertible Mustangs, Mustang HPP or Mustang with Active Exhaust.
