L2 Competition Series Ceramic Coated Muffler- AC4000M-4

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 L2 Series Muffler is 13.5 lbs. lighter than the stock suitcase on the Blast!
