Walker Exhaust Exhaust Muffler 21414

A muffler without any pipes, which are typically universal in fitment. (21414) 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.

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

Fits: 2005-2001 Pontiac Aztek
