The oval body measures 16.000 inches long, 11.000 inches wide, and 5.500 inches high, with an overall length of 29.800 inches.

What It Helps Address

• Loss of OE-style exhaust tone after muffler failure

Installation Notes and Tips

Verify inlet and outlet diameter, offset inlet location, center outlet location, and overall length before installation. This muffler uses a pipe-connection inlet and does not include clamps. Confirm hanger alignment and tailpipe angle-trim orientation against the original exhaust layout. For best results, compare the removed muffler to Walker 21228 before final installation on the vehicle.
