Muffler shells take the brunt of road spray and salt exposure, so they're frequently the first exhaust component to need replacement on an aging vehicle.
Walker 21690 Highlights:
- It's built to fit 2010-2017 Chevy Equinox, GMC Terrain without requiring any cutting or welding.
- Its aluminized-finish stainless steel shell resists the corrosion that eventually rusts out a factory muffler.
- Body dimensions of 15 in. x 8.81 in. x 4.25 in. in an oval body are sized to match the factory muffler cavity.
- A pipe connection inlet (2.25 in.) and a pipe connection outlet (2.25 in.) line up with the factory connection points.
- At 19 in. overall, it matches the factory muffler's footprint.
- This part is sold individually.
