Speedwerx Lightweight Mufflers // Ceramic Coated

• Stock Blast Muffler- 18.45#
  
• Speedwerx Lightweight Muffler- 9.05#
• Weight Savings- 9.4# !

All of our mufflers are designed to reduce weight while keeping sound levels as low as possible. Our mufflers have more bark than stock units but we try not to make them too obnoxious. We always have performance on our minds and our mufflers will either perform the same or better than the stock system. Our mufflers utilize the stock outlet location and require no major chassis modifications for installation.

• Stealth Black Ceramic Coated- AC4000M-3-BC
• Bright Silver Ceramic Coated-  AC4000M-3-CC 

The stock muffler on the new Arctic Cat Blast 4000 series machines is the same fitment as the current 2-cylinder models, so we put our Standard Lightweight and L2 Competition Series Mufflers on one to see what they would sound like with the 65hp, 400cc single-cylinder EFI 2-stroke engine. Much like the 6000 and 8000 models, you can add a more aggressive sound and remove a pretty good chunk of weight in a matter of minutes.

Our Lightweight Muffler cuts 9.4 pounds from the Blast while maintaining a very trail-friendly sound level!
