Aeroturbine 4" Stainless Steel Resonator AR40

For us, there is no question what the answer would be for any of our staff if asked what our favorite muffler is. We have been AN Aeroturbine muffler distributors for over 10 years now and every truck in our parking lot has one of their mufflers installed. Aero Exhaust has been through some turmoil over the past couple of years, but they are BACK! And we are so pleased to be able to offer their superior muffler design again.

For those unfamiliar, these mufflers are designed to create an internal vortex in the exhaust to literally "suck" the exhaust away from the engine, reducing exhaust gas temperatures. Beyond this attribute, these mufflers create a unique sound, and when opting for any of the "XL" resonated versions, they are awesome at cancelling out any drone inside of the cab. And finally, the construction is a work of art. Built out of T304 stainless steel inside and out, without any of the traditional packing used by many other manufacturers that is notorious for breaking down over time.
