Product details

The Flowmaster® American Thunder® Axle-back exhaust system for the 2018-2026 Jeep Wrangler JL is perfect for the person looking for maximum performance and ground clearance. The 2.50-inch tailpipe features a mandrel bent 409 stainless steel tailpipe finished off with a 3.00-inch polished 304 stainless steel tip and fits both 2 and 4 door models with the 2.0L Turbo or the 3.6L engine. This system replaces the factory transverse muffler reducing weight, improves ground clearance, and provides a moderate sound level that is not offensive or will be considered loud by most people. Because this system tucks the tailpipe up high, an aftermarket metal bumper is generally recommended. The exhaust system is covered by our Lifetime Limited Warranty. Designed for a perfect fit, this system includes all necessary parts and hardware for easy and quick installation you can do at home in about 15 minutes. Fits 2018-2026 Jeep Wrangler JL, 2.0L Turbo or 3.6L engine. No muffler. Both 2 door & 4 door models. - Moderate sound Flowmaster American Thunder Axle-back Exhaust System

BEFORE YOU ORDER

A few things to know.

How do I order these parts?

Add your exact parts and delivery details, then continue to payment. Eligible orders show the final parts, shipping and tax total and a PayPal button here after automatic checks. Freight, oversized, custom and uncertain items go to JuiceBuilt for a quote. You are charged only after approving PayPal; supplier orders are submitted separately after verified payment.

Does a part number guarantee vehicle fitment?

No. Product descriptions are supplied by the manufacturer. Check the manufacturer application information for your exact vehicle, engine and supporting modifications. Online checkout requires your exact-part fitment acknowledgment. Contact JuiceBuilt before ordering if you need fitment help.

Is the stock shown reserved for me?

No. Availability is a dated supplier snapshot. Inventory can change, and adding a part to your build does not reserve it. Availability and delivery are checked again before payment. A supplier order is confirmed separately after payment.

What about shipping?

Eligible standard-size parts orders with a parts subtotal of $100 or more receive free standard shipping. The minimum applies after coupons and other discounts.

The same $100 minimum applies to all brands, including Aerospace Components.

Oversized and freight items are excluded from free shipping at every subtotal, including carbon doors, hoods, trunks and similar large panels. Their shipping charge is quoted separately before payment.

Shipping for orders below $100 is calculated before payment.

Online checkout is initially available for US delivery addresses. For other countries, contact JuiceBuilt for a manual quote before payment.
