Speedway Motors 9301007 Details

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 aggressive 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 horsepower 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
  • Offset outlet

Overall Assessment

Customers highly rate our product for its powerful, aggressive sound quality at a competitive price point. The mufflers conveniently fit well and are compact enough to easily install out of sight. Customers frequently compare the product favorably to more expensive brands, particularly noting its superior sound. While there were some reports of the black coating rusting, the overall material quality is still appreciated. Some customers suggest that installation may require some technical skills due to the size of the inlet and outlet. Despite this, our muffler remains highly recommended for its sound quality and value for money.

Good product, installation difficulty

A solid product. A bit loud but we'll see on the road. Downside, the inlet and outlet are 16 g steel. Quite a bit oversized so a loose fit. Can't be tightened with standard exhaust clamps and the joints needed to be tack welded to prevent separation and rotation. Not great for your average mechanic. Have purchased Speedway for 30 years so a bit disappointed. A recommendation with reservations.

Great sounding mufflers.

Love the sound these muffs make on my 383 Chev., however, the black coating is rusting in only 4 months and < 4,000 miles. Will need to sand and paint, except they're mounted on their sides, close together on my truck.

I wanted an aggressive sound and that is what I got with these, they are compact enough that they easily tucked up and out of sight and didn't cost an arm and a leg to get, I would definitely buy again.
