STILLEN builds its 2024 and newer Tacoma cat-back in three configurations, all from 3 inch 409 stainless steel and made in Costa Mesa, California. STILLEN quotes dyno-proven gains of 22 WHP and 34 lb-ft at 3,400 RPM, plus a deep, refined tone with little cabin drone. Laser-cut flanges are meant to give a leak-free fit, and the system carries a limited lifetime warranty.
The Rear Exit (509243 polished tip, 509244 black tip) was developed for leaf-spring equipped trucks but also works on coil-spring trims. The Side Exit (509240 polished, 509241 black) is the factory-style exit behind the rear driver-side tire and is for coil-spring models only. The Off-Road Dump (509242) exits ahead of the axle with a 90-degree turn-down tip for departure angle on lifted trucks, rock crawling or aftermarket bumpers. It weighs 22.2 lb against 50.3 lb for the OEM system.
Fitment
STILLEN offers a version for nearly every 2024 and newer Tacoma cab and bed configuration. Pick Side Exit only on coil-spring trucks. If you are unsure which exit suits your trim, call us before ordering.
Questions before you order?
Fitment questions are easier to settle before the box ships. Call or text Carl & Anton at (920) 249-7744 or use the chat — real humans in Sheboygan, Wisconsin, not a call center.
