MBRP XP Series Street Cat-Back Ex. Kit (11-14 GT)





  • Polished cat-back exhaust
  • Rugged 16 gauge T409 stainless steel
  • 4" polished tips


MBRP's Street cat-back exhaust system for 2011-2014 Mustang GT is a great starting point to getting the most from cold air intakes, tuners and other bolt-ons. Expect gains of around 3 HP and 10 TQ by bolting on an MBRP cat-back. MBRP's cat-back was designed to maximize exhaust flow and minimize exhaust temperatures. Rugged 16 gauge T409 stainless steel construction can withstand what the road throws at it, whether it be salt, rocks, tar, grime, etc. The cat-back is polished to give off a mirror finish and looks great exiting the rear of your Mustang with 4" tips.

MBRP cat-backs produce notable decibels without making your ears ring. Exhaust notes are subtle and civilized while normal driving but aggressive when you increase the gas. Minimal bends, smooth piping and high flow mufflers increase CFM and add a boost of horsepower. Stock cat-backs offer 502 CFM but MBRP is able to create 604 CFM with their Street cat-back. One-piece over-axle pipes allow for easy install making it easy, even for the DIY mechanic.

XP Series exhaust systems are designed and built to stand up to the harshest road conditions. Construction comes from T409 stainless steel.


MBRP XP Series Stainless Steel 3" Street Cat-Back Exhaust System is designed for 2011, 2012, 2013 and 2014 GT Mustangs.
