Add more horsepower and performance to your 2015-19 Mustang with a new midpipe or x-pipe from Late Model Restoration. By replacing your restrictive resonator with a high flow x-pipe, you get more exhaust flow which helps free up power and performance in your Mustang. These midpipes are wider in diameter and are offered with or without catalytic converters. Choose a catted x-pipe to keep your S550 emissions legal with two high-flow catalytic converters. Go cat-less with a Mustang offroad x pipe for more power and a deeper exhaust tone. These midpipes are offered in various finishes to get your exhaust system looking and sounding great! These midpipes fit 2015-19 Mustangs.
