Product Description

Flowmaster Performance
Flowmaster has created another high quality kit that produces aggressive exterior sound with a moderate interior sound. This 2015-2016 Mustang EcoBoost cat back exhaust kit will provide the sound along with the power you expect from Flowmaster products. This kit is constructed of 2.5" tubing that increases into dual 3" tubing for maximum flow. The 3" tubing then flows into a pair of high flow Outlaw series mufflers. These mufflers give you the best sound and performance you can ask for!

Flowmaster Quality
Flowmaster has constructed this 2015-2016 Mustang EcoBoost cat back exhaust from 409S stainless steel for long lasting quality and durability. The tubing and mufflers are topped off with a pair of 4" polished stainless steel tips that will look great coming from your rear valance.

NOTE
Flowmaster considers this exhaust in the American Thunder series, but this kit includes Outlaw series mufflers.

5 Stars   Great price, flowmaster quality, turbo beast sound!!

Got this for my ecoboost 6spd. This exhaust is just what I was looking for. It's loud when you get on it, not when you don't. No drone on the highway at all. It has a nice deep tone like the magnaflow at a more reasonable price. Yes it sounds like a 4 cylinder turbo beast, that's what I wanted because that's what I bought in the ecoboost. Reminds me of my old SRT-4. I still have the stock downpipe so you really have to get on it to get pops and crackles, so the cops will leave you alone if you don't run around town at 6000 rpm lol. Easy install, easy to align.

Yes, I would recommend this item to a friend!

Through use of these dyno's, Flowmaster's engineering staff can track the complete engine cycle in millionths of a second and can obtain exact technical data of each degree of cam rotation, from induction to the tip of the exhaust system, while also showing the power numbers that really matter, the power numbers "to the ground."
