Universal 4" x 23" Stainless Twister Muffler (71799)

Fit: Any Truck with a 4" Exhaust System

Flo-Pro Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.

The Twister Muffler 71799 by Flo-Pro is a universal muffler add-on for any 4" exhaust system. At 23" long it is the extended version of the 18" 71299, built on the same 5" round body and the same high-flow dual-path design. The Twister keeps your exhaust quiet enough for the street but does not restrict the flow like your OE muffler would.

It's designed to meet most track requirements and works as a resonator on diesel applications. Flo-Pro has tested these vs open headers and has found an insignificant loss of power when adding the twister muffler system!
