Flowmaster 817713 Outlaw Axle-Back Exhaust Kit 3 Inch 409 Stainless Steel 4 Inch Polished 304 Stainless Steel Tips Compatible with 2015-2023 Ford Mustang 2.3L Ecoboost or 3.7L V6 Coupe Convertible

As for shipping, it came earlier than expected. Installation was a breeze. It took me roughly 30 minutes to install. I only did Axle-Back so I could see how it sounded. I really didnt wanna sound like a import with that horrible fart can sound. I was looking for a deep sound, something you would expect from a mustang. My personal opinion, this is as close as you get with a 4 banger. I'm very happy with the craftsmanship, Installation process and sound. Flowmaster lived up to their name with this setup.

I ordered these for my wife’s 2016 3.7 Mustang, they came with clear instructions and were fairly easy to install. I used a set of oil change ramps to gain clearance and it worked fine but would be easier if you have access to a lift. A reciprocating saw with a new metal cutting blade goes through the stock pipe with ease, just make sure to use a file to clean up the rough edges before installing the new pipes. I’m not a skilled mechanic and I had them on in just over an hour. The sound is better than I expected, I didn’t know you could get that kind of sound out of a V6! It is a little loud inside upon acceleration, but that’s what you want from a Mustang and Flowmaster!

This flowmaster exhaust sounds amazing on my 2020 mustang ecoboost. Highly recommended to all the mustang owners

Easy to install, well packaged and sounds perfect. This was for my sons car. I only used Flowmasters on my 1,200 HP Chevelle, but I did not know how they would sound on this Ecoboost 4 cylinder. To my surprise they sound amazing! Well worth it and great quality.

The media could not be loaded. I bought this exhaust along with a Y-pipe and the sound is great on my 2019 mustang ecoboost. I received the package in pretty rough shape and the clamps must have fallen out in transit and the seller shipped me new clamps right away. Highly recommend!

Made my 2020 Ecoboost way more fun and louder, Planning to add a Y- pipe and catless downpipe in the future, so this was the best axle-back I have ever heard for the EcoBoost!!!!!

I purchased this item and had it professionally installed. My mustang EcoBoost boost sounds great.

The Mustang sounds Great! If you don’t want your car to get attention when you roll by, don’t buy these!
