Description of Walker 17197 SoundFX Universal Muffler
RESISTS CORROSION -- Aluminized steel construction and internal drainage system helps reduce corrosion. BUILT TO LAST -- Internal partitions and mechanically joined tubes allow expansion and contraction during temperature changes to minimize distortion while spun-locked heads and OE-style spot welds provide stability and longer service life. FLEXIBLE SOLUTION -- Customizable design features expandable bushings for easy fitment and may require specialized fabrication and/or welding for installation. FACTORY SOUND -- Louvered tubes help reduce radiated noise for factory-style sound quality compared to straight perforated tubes. GET MORE MILES FROM YOUR MUFFLER -- Designed and tested to extend muffler life.
Fits 2 on a Chevelle 69 with headers. (Headers, then short pipes, mufflers, no exhaust pipes, dual exhaust). Still too loud for me. Maybe good for cars with catalytic converters, or maybe good with full exhaust including tailpipes. Good price.
