Universal FLO-PRO 4" Stainless Twister Muffler (71299)

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 71299 by Flo-Pro is a universal muffler add-on for any 4" exhaust system. The Twister muffler uses a high-flow dual-path system to keep your exhaust quiet enough for the street but doesn't 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!
