Walker Exhaust Exhaust Muffler 21423
A muffler without any pipes, which are typically universal in fitment. (21423) by Walker Exhaust
The only broad-market muffler with 100% stainless-steel construction, Walker ® Quiet-Flow ® SS mufflers feature precision fit, superior flow and OE-style sound. Quiet-Flow SS mufflers are available for most domestic and import vehicles.
