Ryan A. ★★★★★

The install was straightforward on my 2006 4Runner, and the difference in sound is night and day compared to the stock setup. I especially love how the tone stays clean and never drones on the highway.

Sofia W. ★★★★★

That deep, mellow growl at startup made me smile immediately — no drone on the highway either. The polished stainless tip looks great under the bumper, and I can feel a slight throttle response improvement over stock.

Kevin T. ★★★★★

Bolted it on in the driveway in about two hours with basic hand tools, and the fitment was spot-on for my 4.7L. The deep tone at cold start settles into a nice rumble on the highway without any drone, and I've noticed a slight but real throttle response improvement. Definitely the punchiest upgrade
