Detailed Description

This Walker exhaust muffler, part number 21052, is engineered as a specific-fit replacement for 2012-2015 Cadillac CTS, front. The Quiet-Flow SS line focuses on stainless-steel durability, precise fitment, and controlled exhaust tone, making it a practical choice when replacing a worn or damaged muffler on the Cadillac CTS. The oval body measures 16.000 inches long with an overall length of 20.00 inches, and the offset inlet and outlet configuration supports the original exhaust routing. This part cross-references Monroe Shocks & Struts (e.g., 25915813) for the same application.

What It Helps Address

  • Exhaust noise from a deteriorated muffler.
  • Corrosion-related muffler replacement needs.
  • Fitment issues when replacing a specific application muffler.
  • Loss of OE-style exhaust sound after component wear.

Installation Notes

Verify the inlet and outlet orientation, offset layout, and 2.250-inch connection size before installation. This muffler does not include clamps or hangers, so confirm the exhaust system is prepared for the existing mounting setup. Fits 2012-2015 Cadillac CTS, front.

Quality Assurance

Walker Quiet-Flow SS mufflers are part of a broad-market stainless-steel exhaust line developed for precise fit and OE-style sound.
