5" In, 6" Out Flowtech Signature Sports Universal Truck Muffler

The ever-popular, renowned Flowtech Signature (previously Flowtech Performance) sports style universal truck muffler, with a 6" (152mm) ID outlet, to accommodate larger, non-reduced chrome stacks. 

Designed and manufactured in Australia for Australian conditions, Flowtech Signature mufflers feature:

• High heat painted finish for added durability
  
• Aluminised steel construction for improved rust resistance
• 30% thicker material (compared to Flowtech Mid-Range mufflers)
• Fully welded (not folded) seams for added longevity
• Reinforced end plates for superior strength (for larger, heavier chrome stacks)
• Domed end plates to prevent moisture build up
• Fibre glass packing for superior tone - no hollow sound
• Laser-engraved model plates to ensure consistency of supply
• 2 year manufacturer warranty.

The straight through design of the M1044-506 helps deliver:

• Awe-inspiring sound
• Enhanced performance
• Improved fuel economy
• Unrestricted flow. 

For universal application (most trucks with a 10" x 44" muffler setup with 6" outlet), but many of our customers have found them particularly successful on Kenworth, Western Star and Freightliners with Cat C15 or Cummins Signature series engines.

We have had feedback from operators reporting a 15-20L fuel saving per day - this clearly depends on driving style, kilometres travelled, load sizes and other variables, but with the current high fuel prices, these mufflers should pay for themselves in no time!

These are heavy duty mufflers for heavy duty trucks! 

Available in a full range of barrel lengths, barrel diameters and inlet/outlet sizes, and the entire Australian-made Flowtech range of mufflers can be customised to your specific requirements.
