Borla

There are performance mufflers, and then there are Borla performance mufflers. Borla ProXS mufflers are made with fully-welded S304 aircraft-grade steel, which will never rust, and come with a Million-Mile warranty.

The Borla ProXS features straight-through construction for high airflow and CFF continuous filament fiber acoustical materials for excellent sound control, all packed in a sharp-looking oval case. In this top-of-the-line dual truck exhaust kit from Magnum Exhaust, we pair this remarkable muffler with mandrel-bent S409 stainless tailpipes, stainless turnouts, and stainless tips.
