This is hands down the most aggressive, yet livable catback for my 18 GT PP1. I'm a Roush guy myself, had a catback on my 2010 GT, but for 2018, Roush took it to another level. Everything was as described and perfectHelpful (3)

Excellent addition to any 18-19 S550
Bought this for my wife for her 18 S550. I was a little skeptical, but it was the sound she wanted. Install took under an hour on jack stands. on first start up, the cold start is brutally loud. Even louder than my S197 with LTH and full borla exhaust. It does calm down a bit after it's warm. Has a great sound and no drone. I would recommend to anyone that is looking for a quality system with no drone.Helpful (3)

Best part of this exhaust is when you're cruising there is zero drone and you can comfortably listen to music, etc. However, it's borderline waking up my neighbors when cold cranking and gets loud in a hurry when you are driving aggressively. Under normal driving it definitely is noticeable and has a great rasp to it. I have zero regrets and for the price it's a no brainer that I would buy this again.Helpful (1)

These have a really nice and raspy tone. Every morning when I turn the car on the cold start they put a smile on my face. This exhaust is very loud, but you can still cruise without making too much noise. And there is no drone from this exhaust.Helpful (1)

Unique exhaust sound
This has got to be one of the best exhaust I've heard on a mustang. I love a car with a good exhaust system but this is just about the best sounding exhaust for a mustang period. The exhaust note changes as u drive so if you are light on the pedal its gonna give you a nice deep grumble. If you accelerate a little quicker you get a higher pitched sound but still deep. If your just cruising along you almost can't hear it. When you down shift you get this deep growl. This is an amazing exhaust and I can say that you will turn heads and get compliments everywhere you go.Helpful (15)
Will this modification cause the service engine light to turn on??
This will not cause a check engine light.
Will I need a tune with the Roush Catback? I have a 2018 PP1 GT.
This does not require a tune.
Can this go on a 2016 3.7 v6?
This is designed only for the 18-20 Mustang GTs. We do not recommend use on a V6, or years outside of the guaranteed fitment.
Just installed this system on my 19' and the mufflers and tips seem to be hanging about an inch low. Any tips on how to raise these?
Was wondering if there is any drone with this set up?
Generally speaking, customers do report some drone with this system.
We cannot offer special orders, you can only purchase this kit, and any other kit for that matter that we offer, as they are advertised.
This would remove the functionality of your active exhaust, but if you're looking to install something aggressive, this will do the trick.
A long tube header that includes a 2.5-inch connection pipes or a 2.5-inch step-down pipe would work this catback.
This exhaust is 2.5 inches in diameter.
This exhaust weighs 27 pounds.
This will work on your car yes.
Sound would be a subjective measure. Both exhausts are very loud. We recommend listening to sound clips of both to hear what you think is louder.
