Does the PP4178-56 keep the catalytic converters?

Yes — it's a with-cats package, so the catalytic converters stay in the system rather than being deleted.

Is this a full header-back system?

Yes. It includes the headers, cats and a 3in system with a quad-tip rear, covering the exhaust from the heads back.

Will it fit my 2018-2023 Mustang?

It's listed to fit the 6th-generation Mustang 5.0L Coyote V8 from 2018 to 2023, RHD. Confirm your exact variant with the workshop before ordering.

The Pacemaker PP4178-56 is a 3in exhaust package for the Ford Mustang (6th generation, 2018-2023) 5.0L V8 Coyote. It combines headers and cats with a quad-tip rear, so it's a header-back build rather than a single section, and the listing notes right-hand-drive fitment.

What does this package cover?

PP4178-56 is the full 3in build for the 6th-generation Mustang: tubular headers off the Coyote V8, the catalytic converters, and a quad-tip rear. Headers replace the cast manifolds at the front, the cats keep the emissions hardware in line, and the 3in pipework carries it through to the four exit tips. Sold as one package, the header-to-cat-to-system joins are matched for the car rather than mixed from separate parts.

What's a header-back system and what does it change?

A header-back run replaces the exhaust from the cylinder heads rearward — headers, then cats, then pipework and tips. The trade-off versus a tailpipe-only change is scope: more of the system is new, so the note and gas path differ more from stock, but the fit is more involved. We publish no power or sound figures, so the honest description is a 3in header-back system with cats and a quad-tip rear — a character change, not a measured one.

Will it suit my Ford Mustang?

It's listed to fit the 6th-generation Ford Mustang with the 5.0L Coyote V8 from 2018 to 2023, and is noted to fit right-hand-drive. Fitment listings can be imperfect, so confirm your exact variant and drive configuration with the workshop before ordering. Recommended retail is $5,228.28.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits header-back packages like this in-house across the Illawarra. We start at the heads with the headers, fit the cat section, then hang and align the 3in system back to the quad-tip rear. Send your Mustang's build and we'll confirm the fitment and book the bay.
