2007-2018 Jeep Wrangler JK mufflers from aftermarket factories like Gibson and Flowmaster unleash a lot of potential in your Jeep Wrangler, including a refreshing boost to both sound and performance for your vehicle’s 2007-2018 Wrangler exhaust. There are enough different models on the market so that you can choose between aluminized steel (low-cost but will eventually rust), T-409 stainless (tarnishes but won’t rust through) and T-304 stainless (practically immune to rust and discoloration. These robust 2007-2018 Wrangler mufflers are typically all-welded for high strength, and feature free-flowing designs that don’t hinder the exit of exhaust vapors. They’re also engineered with baffling and chambering that eliminates annoying droning sounds in the cab, while strengthening your Wrangler’s “voice” to a bass rumble that will make everyone sit up and take notice.
