Make your EcoBoost sound like an EcoMonster

Recommended Posts

Livernois Motorsports has released another expansion of our Thunderstorm exhaust upgrades, this time for the acclaimed 2015+ EcoBoost Mustang. Developed on our shop-owned car, we had one mission in mind, Offering unmatched American quality with expansive, and customization offerings of exhaust upgrades on the market for these vehicles. Our Downpipe and exhaust offerings have many distinct options to cater anything from stealthy daily driver, to all-out race car, with everything in-between. Our Downpipes are available in catted, and non-catted versions, and in addition to that we have developed 3 different stages of upgrades on the exhaust system.


Thunderstorm Stage 1 includes our high flow, USA Made 304SS Downpipe, with your choice of catted, or off-road race configurations, to use with the factory cat-back system.


Thunderstorm Stage 2 includes your choice of catted, or off-road Downpipe, plus our performance mid section, which increases the pipe sizing of the mid section, while eliminating the factory resonator for that next level of performance for your Mustang.


Thunderstorm Stage 3 expands upon our stage 2 upgrade by including our Thunderstorm Rear-Section, allowing the entire exhaust system to have increased diameter piping for another bump in performance.

Any of these 3 variations can be combined with our optional quick change race-dump which eliminates all of the cat-back exhaust system's weight, and performance robbing restrictions leaving you with a true 3" race system unlocking the maximum performance potential from your EcoBoost Mustang!
