2015–23 Mustang 5.0L Coyote ARH Bottleneck Eliminator System

Features & Benefits

• ARH Bottleneck Eliminator system designed for aftermarket cat-back exhausts, removing the 2-1/4-inch restriction at the cat-back connection.
• Made in the USA from 304 stainless steel with 3/8-inch laser-cut flanges, hand-ported TIG-welded inlets, optimized routing and merge collectors with scavenger spikes.
• Choice of 1-3/4-inch or 1-7/8-inch primary tubes and catted or non-catted configurations. Mark-and-cut connection; ARH states no welding is required.
• Catted versions use severe-duty 300-cell catalytic converters. Ask before ordering about ARH's optional G-Sport upgrade.

Fitment Notes

Tell us your cat-back brand and outlet dimensions before ordering so the ARH X-pipe outlet can be sized correctly. ARH directs Corsa cat-back owners to its Corsa-specific Direct Connect system. ARH states this system is manufactured exclusively for racing purposes; installation eliminates legal use on public roads and highways. Built to order; contact us for lead time.
