Product Details

MagnaFlow 11226 is part of the Satin Finish Oval Exhaust Muffler line, a product line focused on straight-through exhaust construction for custom fabrication work. The oval stainless steel body, perforated core, and acoustic packing are engineered to support a deep exhaust note while maintaining a free-flowing path through the muffler. This configuration is well suited for drivers building or replacing a custom exhaust on a 2005-2015 Toyota Tacoma, 2000-2003 Chevrolet S10, or 2000-2003 GMC Sonoma.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Uses

• Replacing a restrictive or damaged muffler on a custom exhaust system
• Changing exhaust tone on a Toyota Tacoma, Chevrolet S10, or GMC Sonoma
• Supporting a center-inlet, offset-outlet exhaust routing
• Restoring stainless steel muffler construction in a fabrication project

Installation Notes

Verify inlet and outlet sizing before welding or clamping the muffler into place. The reversible design gives installers more flexibility when aligning the center/offset configuration, but hanger placement must be planned separately because no hanger is included. Confirm available clearance for the oval body dimensions and overall length during mock-up.

Quality Assurance

MagnaFlow uses a stainless steel body, stainless mesh, and acoustic fiber fill to support consistent exhaust flow and tone control. Part number 11226 is built for custom exhaust use where material durability and internal flow design matter.
