So you bought yourself a Ford Bronco, but aren’t too happy with the exhaust note it gives. Perhaps you want something that’s got a deeper tone, but isn’t too obnoxious. Take a look at the Kooks Street Series Axle Back Exhaust for the 2021+ Ford Bronco. Lethal Performance recently installed this on their 2.7L First Edition 4-door Bronco, and posted info on it to the Bronco6G forum.
Ford Bronco Kooks Axle Back Exhaust: Details
The system gives a comparatively more subtle, deep-toned note that brings out the best in the Ford Bronco, yet remains discrete unless you want it to rev with some added throttle. The black, ceramic-coated tips blend nicely with the rear bumper. And, Kooks supplies everything needed to install the system as well as a custom exhaust hanger to counter the differences between the 2.3L and 2.7L models.
If customers aim to get a more discrete system, Kooks offers an Adventure Series Axle-Back, allowing higher surface clearance. The sound of the system should be relatively similar, though subtle differences will exist as the routing of the pipes is changed to make it a single exit system.
As for the Street Series Axle-Back Exhaust, the system seems to be pretty close to the OEM sound while still providing a bit of amplification, so a step up from the OEM look and note. As far as pricing goes, the Street Series exhaust is available for $892.50 currently, though it appears that the system is on sale as of the time of writing. The usual price is $1,050. If the high clearance Adventure Series is more your style, that’s available for $807.50 with the sale but is usually $950.
Kooks also states on the product pages that high demand and supply chain issues will cause delivery setbacks, and customers will have to wait beyond the usual 6 weeks to have their orders fulfilled.
