For 2015 Mustang owners that already own an aftermarket catback, you now have the ability to install ARH's header system and eliminate the serious 2-1/4" restriction at the catback inlet. We call it the Bottleneck Eliminator System. Along with the ARH Long Tube headers, available in 1-3/4" 1-7/8" or 2" primary sizes, comes with the X or optional H-Pipe that splices easily into your aftermarket catback at 3". NO MORE RESTRICTION!
