Fit: Any Truck with a 4" Exhaust System
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!
Features:
- Fits ANY 4" Exhaust System
- T409 Stainless Steel
- High-Flow
- Continuous Spiralized Design
- Meets Most Track Requirements
- Less Restrictive Than Glass Packed Designs
