Muffler Specs:

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
  • Design eliminates the "drone" found in single baffle designs
  • Compact 9.75" x 13" x 4" body with an overall length of 19"
  • Black hi-temp coating
  • Offset inlet
  • Centered outlet
  • Fits 2.25" diameter exhaust pipe
Some parts are not legal for use in California or other states with similar laws/regulations
