ETL INDUSTRIES Exhaust Muffler System Kit for 2007–2018 Wrangler JK 2/4-Door — 2.5" High-Flow Inlet, Matte Black 304 Stainless Tip

If you own a 2007–2018 Jeep Wrangler JK (two- or four-door), this bolt-on muffler system from ETL INDUSTRIES gives your Jeep an instantly bolder exhaust tone, upgraded rear styling, and long-lasting stainless construction. Engineered specifically for the JK chassis, the kit pairs a 2.5" inlet high-flow design with dual-wall 4" 304 stainless tips finished in matte black, offering a balance of sound, airflow, and visual aggression without permanent body modifications.

How will this muffler system change my Wrangler's sound and performance?

The ETL system is tuned to produce a deeper, more aggressive exhaust note while maintaining drivability and backpressure appropriate for street use. It provides improved exhaust flow through a larger 2.5" inlet and free-flowing internals, which can feel more responsive under acceleration.

• Throaty, aggressive exhaust tone at idle and load.
• 2.5" high-flow inlet reduces restriction compared with stock mufflers.
• Dual-wall 4" tips enhance exhaust exit and visual presence.
• Designed to preserve everyday driveability and low-end torque.

What materials and finishes protect the system from corrosion?

ETL INDUSTRIES uses 304 stainless steel for the visible tips and corrosion-prone areas, plus a durable high-temperature matte-black coating on external surfaces. This combination resists rust and road debris while keeping the system visually consistent with aftermarket bumpers and accessories.

• 304 stainless steel dual-wall tips for long-term corrosion resistance.
• High-temperature matte black spraying prevents surface oxidation.
• Welds and joints built to withstand off-road conditions and salt exposure.

Is installation difficult and will I need to modify my Jeep?

Installation is designed to be straightforward with a no-cut, no-drill approach that uses existing mounting points on the Wrangler JK. While the kit is intended for bolt-on fitting, ETL INDUSTRIES recommends professional installation to ensure correct alignment and sealing.

• No cutting or drilling required for standard JK rear assemblies.
• Uses factory hangers and attachment locations for a secure fit.
• Professional installation recommended to ensure optimal exhaust alignment and clearance.

Will this muffler system fit every 2007–2018 Wrangler JK configuration?

The kit is manufactured to fit the full range of 2007–2018 Wrangler JK models, including both two-door and four-door variants and most common factory and lightly modified setups. Confirm compatibility with your model year before purchase to avoid fitment issues—especially if your vehicle has significant suspension or bumper modifications.

• Works with most factory rear bumper layouts and common aftermarket bumpers.
