Using 1-7\/8-inch 304 stainless steel primary tubes and a 3-inch collector with integrated merge spike, the M24H3CATLG is engineered for enthusiasts running a non-Stainless-Works aftermarket cat-back exhaust who want the performance and sound of a proper long-tube header without replacing their existing system. The aftermarket connect 3-inch outlet fits most aftermarket cat-back brands including MBRP, Corsa, Borla, and similar.

If you already own an MBRP, Corsa, Borla, or similar brand cat-back, this is the header variant that connects directly to your existing system without requiring a full exhaust replacement. Some fitments may require minor trimming for precise alignment. If you are retaining the OEM Ford factory cat-back, see the M24HCAT (factory connect) instead.\u003c\/p\u003e\n\u003ch4\u003e1-7\/8-Inch Primaries: Optimized for Street and Track NA Builds\u003c\/h4\u003e\n\u003cp\u003eThe 1-7\/8-inch primary tubes on the M24H3CATLG are the most popular choice for naturally aspirated and mildly modified 5.0L Coyote builds. Smaller primaries maintain higher exhaust velocity at low and mid RPM, improving throttle response and mid-range torque delivery. For forced induction builds where peak flow at high RPM and under boost is the priority, the 2-inch M242H3CATLG is the correct choice.\u003c\/p\u003e\n\u003ch4\u003eFitment for 2015-2026 Ford Mustang GT\u003c\/h4\u003e\n\u003cp\u003eThe M24H3CATLG fits the \u003cstrong\u003e2015-2026 Ford Mustang GT with the 5.0L Coyote V8 only\u003c\/strong\u003e.
