MagnaFlow Competition Series cat-back 16605 for 2005–2009 Ford Mustang 4.0L aims for an aggressive, attention-grabbing exhaust note while improving flow. Constructed from corrosion-resistant stainless steel with mandrel-bent 2.5" tubing and two straight-through mufflers, it exits in a dual split rear arrangement with 3.5" polished double-wall tips. The direct-fit design simplifies installation; check local noise regulations before use.
