American Racing Headers 2015-2017 Mustang 1-7/8" x 3" Long Tube Headers and Catted X Pipe (Bottleneck Eliminator System)

American Racing “Bottleneck Eliminator” which includes our Long Tube headers with X or H-pipe designed to work with aftermarket catbacks. This unique set up eliminates the 2-1/4” restriction all aftermarket catbacks are forced to have on the inlet side. X or H-Pipe outlet is 3” ID.

NOTE: FOR AFTERMARKET CAT-BACKS ONLY! Requires cutting a small section of the aftermarket catback on the inlet side to eliminate the restriction.
