Universal 5" Stainless Twister Muffler (71600)

Fit: Any Truck with a 5" Exhaust System

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

The Twister Muffler 71600 by Flo-Pro is a universal muffler add-on for any 5" 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!

  If I maintained my 5 inch Fiberglass packed muffler, do you recommend the Twister be installed before or after the muffler?

  You should install the Twister before your fiberglass-packed muffler, placing it as close to the turbo downpipe as possible.

  Does this muffler increase more HP and TQ over a turbo back exhaust and increase fuel economy?

  These mufflers are designed for sound attenuation and exhaust flow improvement rather than directly increasing HP and torque - you won't notice and performance gains but there's a slight potential increase in fuel economy; but not significant.
