    Versatile Muffler. If you're looking to upgrade your 2007-2018 JK Wrangler's muffler to a high performance type without breaking the bank, the Flowmaster Super Flow 44 Series Aluminized Steel 2.5-inch Muffler fits the bill, generating powerful sound and improved scavenging. The aluminized steel keeps the cost lower, and, though it will eventually rust, will serve faithfully for years. The Flowmaster Super Flow 44 is a deep-sounding, aggressive component whose interior Delta Flow delta deflectors generate the sound, keep the interior noise mellow, and assist the system in venting exhaust gases swiftly. This twin chambered system is equally suited for off-roading and street use.

    Quality Design. The Flowmaster Super Flow 2.5-inch Muffler is made with performance in mind, with robust 16-gauge walls and MIG welded seams that withstand high heat and pressure. The part is made from high-grade aluminized steel with a black powder-coat finish. The pipe connections of this 19-inch muffler measure 2.5 inches, and its setup is single-in, single-out (with a 2.25" offset inlet and 2.25" centered outlet). 100% made in the USA, this component is covered by a 3 year warranty.

    Application. The Flowmaster Super Flow 44 Series Aluminized Steel 2.5-inch Muffler is designed for fitment to JK generation 2007-2018 Jeep Wranglers.

            Completely rusted out!

            I got this muffler put on in August, and by March the whole thing is almost nearly rusted out. Granted, NY winters are harsh but I still would've expected it to last longer than 7 months.

            Was a great addition to my Jeep!

            It was a great addition weighting less and saving more room under my jeep, it also gives it great sound with a little extra noise but not obnoxiously louder!

            Flowmaster Super 44 Muffler

            Easy fit and sounds good. Not too loud but definitely much throatier than stock. Also, I noticed an increase in acceleration and combined with my Banks's cold air intake I am getting better performance and a slight increase in miles per gallon too. All that on a 2007 JK Unlimited with 209K miles. Totally worth it sound and performance wise. Awesome, easy upgrade. Go for it! Greg F.
