Cadillac CTS Performance Exhaust - Rear - Magnaflow - Street Series Cat-Back, Dual Split Rear Exit, Stainless Steel - Polished - 2010-2014. A direct-fit MagnaFlow Street Series cat-back designed to bring a balanced, resonant tone and proven flow improvements to your CTS.
This Street Series 15136 system is built for enthusiasts who want reliable construction and a purposeful sound without excessive cabin drone. It uses mandrel-bent 2.25" main piping, four straight-through mufflers and a dual split rear exit that terminates in four 4" polished welded-on double-wall angle-cut rolled-edge tips. The cat-back layout replaces factory components from just behind the catalytic converters and was developed with 3D scanning for an accurate fit. Expect moderate exterior sound and mild interior levels while gaining a durable stainless steel system backed by MagnaFlow’s limited finish and construction warranties.
