Common Exhaust Issues It Can Address

Installation Notes and Tips
Confirm the vehicle is a 2013-2015 Chevrolet Spark before ordering. Match the offset inlet and offset outlet layout, the 2-bolt welded flange inlet, and the angle-trimmed tailpipe outlet to the existing exhaust configuration. Because this is a specific-fit muffler, installation is most straightforward when the original routing and hanger locations are intact. Part number 21227 should be verified against the removed component before final installation.
