Product Description

Mustang GT Magnaflow Street Series Catback
Add a smooth exhaust note to your Mustang while increasing horsepower and torque at the same time with this 2018 Mustang GT Street Series Catback from Magnaflow! The factory catback and resonator restrict the exhaust flow, limiting the power output of your 2018 Mustang GT. Magnaflow designed this catback and mid-muffler to open up the exhaust allowing for increased airflow, leading to more power and a much deeper than factory exhaust note!

Quality Construction
Magnaflow constructed this catback from 3" mandrel bent tubing for the best possible airflow, to increase the horsepower and torque! Included in this kit is a straight through style mid-muffler that takes place of the factory resonator for a deep exhaust note, as well as the flow tubes and two 4x9x14" mufflers featuring 4" quad polished exhaust tips. Designed to bolt on to your 2018 Mustang GT without any modifications needed, this catback comes with the 4 clamps to hold the exhaust in place as well as pre-installed exhaust hangers for an easy installation! Pick up this kit today from LMR and start turning heads everywhere you go!

Mustang Dual Exhaust Mode Valves
Included in this kit are 2 dual exhaust valves that allow for the active exhaust to still be utilized. Also included are 2 valve delete tubes that go in place of the active exhaust valves for a straight through dual design, if you are not wanting to keep the active exhaust on your Mustang.

Lifetime Construction Warranty
Magnaflow stands behind their product offering a lifetime warranty on the construction of the catback.

You will need to re-use the factory exhaust hanger bushings that you remove from the exhaust for proper installation.
