Looking for a great sounding muffler that won't break the bank? Speedway Welded Chamber mufflers offer many high-end features at a budget price. These 2-chamber mufflers provide an agressive exterior tone while eliminating the interior "drone" found in single baffle designs. Plus, the twin baffle design creates a scavenging effect to help pull the exhaust through the muffler, increasing horspower and torque. They feature a fully welded steel case with no internal packing to burn up or blow out. Quality materials and construction combined with a black hi-temp coating ensures long life and durability.

  • Heavy 16-gauge material with fully welded seams
  • 2-chamber design improves exhaust scavenging over other muffler designs
  • Twin baffles reduce interior noise levels while delivering deep, powerful tone
