This catback uses a crossover for an improvement in flow over the stock exhaust. Finishing the system off we utilized polished tips with a double wall conical style.

    Best Catback for the Eco Mustang

    Posted by Casey on Mar 28th 2023

    This is hands down the best catback system for the EB Mustang. It provides a deep, aggressive tone that is controlled down low and up top. Unlike other systems, this one remains controlled up top without that nasty uncontrolled rasp of other systems. Gives off a nice deep burble instead. It also lets the turbo breathe and sing like wind upon a chime. Be aware that this system took about a month to mature into its true sound. Nothing wrong with how it sounds after install, just know it will mature with a little bit of time. Since it's a fully stainless steel system it won't have issues overtime with muffler packing wearing out and sounding bad. Plus it will have great longevity if you're a daily driver like me. I used to swear by another company, but was disappointed with how their system sounded on the EB. Found SW and made the switch to the SW Army!
