    The Pypes XFM43 is a 2.5 inch after-cat X-pipe for the 2005-2010 Mustang GT 4.6L. It is mandrel-bent from 409 stainless steel and is designed to work with the factory catalytic converters, installing by cutting the OEM catted downpipes and sliding the X-pipe over them. The crossover design balances exhaust pulses for a smoother tone and stronger flow. Catalytic converters are not included, so the original units are retained.
