This Flowmaster Flow FX Extreme stainless-steel cat-back exhaust system for the 2022-2025 Nissan Frontier with the 3.8-liter engine. This system uses a Flow FX series muffler for a deep powerful sound and increased performance. 2.50 and 3.00-inch mandrel bent 409 stainless steel tubing is used for maximum exhaust flow and durability. Gain up to 5 hp and 5 lb-ft of torque at the rear wheels over stock. The system has a turndown style dump exit right after the muffler to eliminate the over-axle tailpipe. This elimination of the tailpipe helps to improve ground clearance and departure angle when you are driving in more extreme off-road situations. All of the necessary hardware is included and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
