Pypes XFM45 X-Pipe - After-Cat - 3 in Diameter - Stainless - Natural

Compatible with 2011-2014 Ford® Mustang® GT. This product is not created or sold by Ford®.;

The Ford® Mustang® factory cats are actually pretty good high flow cats. Rather than make you replace brand new ones, this specially made X pipe crossover can be added to your existing oem catted downpipes by cutting the downpipes in the appropriate spot and slipping this X-pipe over the existing pipes.;
