Description
Excessive Exhaust Noise. Are you not satisfied with the casual sound of your stock exhaust? Swap it out for the more aggressive Flowmaster American Thunder Axle-Back Exhaust with Polished Tip which offers an overtly loud exhaust roar that is sure to get everyone's attention.
Incremental Speed Additions. The Flowmaster American Thunder Axle-Back Exhaust provides slight speed gains thanks to the ameliorated exhaust tubing which skips the catalytic converters and promotes quicker exhaust discharge.
Scratchproof Stainless Assembly. The Flowmaster American Thunder Axle-Back Exhaust uses heat-resistant 304 stainless steel metal tubes that are checked for their sturdiness and quality to ensure that the tubing doesn't break or crack during installation or even after years of use.
Warranty. This product comes with a limited lifetime manufacturer warranty that covers any manufacturer defects or damages prior to installation. Some limitations may apply to this warranty.
Installation. This product does not require professional installation and would take roughly 1 hour to mount.
Application. The Flowmaster American Thunder Axle-Back Exhaust with Polished Tip fits all 2021-2024 Ford Bronco, Excluding Raptor Models.
