Roush Stainless Steel Axle-Back Exhaust for 2015, 2016, 2017, 2018 and 2019 V6 and EcoBoost Mustangs without the Factory Active Exhaust Option.

This axle-back exhaust from Roush will offer your 2015-2019 V6 or EcoBoost Mustang a distinct and aggressive sound. This highly tuned system will avoid the annoying drone or rasp that can occur with other competitive exhaust systems on the market.

Constructed from 304 Stainless Steel, this axle back exhaust system features an exclusive open-chambered design that will not deteriorate over time, unlike conventional fiberglass packing material. The round exhaust tips are also made from stainless steel and finished with a unique process that provides heat resistance to color change. Like all Roush products, installation is quick, easy, and uses all factory hanger locations. The only necessary modifications to the vehicle is that the factory exhaust will need to be cut off so that the new Roush axle-back can easily install with the provided clamps.

Features and Benefits:
- Fills OEM Ford Rear Valance
- Zero Impact on Emission Devices
- Straight-Thru Design Yields Higher Airflow and Performance
- Full 304 Stainless Steel Construction
- Includes Clamps and Installation Instructions

*Installation requires cutting of the factory exhaust piping. Once the modifications have been made to the factory exhaust system, Installation is a simple bolt-in procedure.

Please Note: Will not fit 2019 EcoBoost Mustangs that are equipped with the Active Exhaust Option from the factory.

Rated 5 out of 5 by from Amazing! Sound is much better for the v6. Better mpg and a noticeable performance increase.

Rated 5 out of 5 by from Does Exactly What They Say It Does! Everything from the install to the results are exactly what CJ's says it is. The video is 100% accurate from putting it all together, to the tone you hear when done. I have no way to measure the exact HP pickup from this mod, but between that and the Roush cold air intake my Ecoboost is far more responsive and peppy.

Rated 5 out of 5 by from Good stuff Installed those to my ecoboost. Well, now it's sounds better then a Chevy Comaro V8 6.2L. Don't trust the sound on the video, in real life is do much better, like a Mustang GT. I defenetly recommend this exhaust. And the price for this is amazing.

Rated 4 out of 5 by from Just about right Fitted in way under an hour and could not be any simpler, they have got the sound about perfect. Any quieter they would be pointless, any louder I would not be comfortable with them. Would have had 5 stars except the clamp kit that came with the exhaust was for the V8 and so I had to cut some more exhaust and split it for temporary packing until I could get clamps the correct size, the tailpipe clamps were OK. I purchased this delivered to Spain and paid 168 euros in extra taxes and costs and that is on top of delivery so they do not come out cheap.

Rated 5 out of 5 by from Outstanding Product! These pipes are exeptional in terms of fit and performance. CJ delivered them on time,for free, and in good condition. A local muffler shop installed them in less than a half hour and they sound great and provided a noticeable increase in power

Rated 5 out of 5 by from Amazing! The video really doesn't do these justice. They make my ecoboost sound amazing compared to the stock pipes. I've noticed a little increase in power too. Had Midas install...charged $99. Well worth the purchase from CJ's and they delivered for free!

Rated 5 out of 5 by from Good Sound for Ecoboost. I purchased Roush previously on my '12 GT and was extremely happy. This system produces a much more aggressive sound than factory and feel it was worth the money. Don't ever think this is going to make your Ecoboost sound like a GT though.

Rated 5 out of 5 by from Very happy The Roush axel back exhaust sounds far better then the sound clips on line. This is the sound that Ford should have given the Eco Boost Mustang to begin with! The installation was so easy it took only 40 minutes and looks good . There is a noticeable increase in bottom end torque plus you will notice how heavy the stock mufflers are compared to the Roush exhaust. I thought when I bought them that the price was a little high but now that they are installed they are worth ever penny !
