Does the PP4178-58 include the rear of the exhaust?

No — it's the headers-and-cats front section, made to suit the factory exhaust. The standard rear stays on the car.

Does it keep the catalytic converters?

Yes. The cats are part of this section, so the emissions hardware stays in the line.

Does it fit left-hand-drive Mustangs?

The listing specifies right-hand-drive only for the 6th-generation Mustang. Confirm your car's configuration with the workshop before ordering.

Stock status: Confirmed on order

The Pacemaker PP4178-58 is a 3in headers-and-cats section for the Ford Mustang (6th generation, 2018-2023) 5.0L V8 Coyote, designed to suit the factory exhaust and listed as right-hand-drive only. It changes the front of the system while keeping the original rear.

What does this part cover?

PP4178-58 is the headers-and-cats front section: tubular headers off the Coyote V8 plus the catalytic converters, sized at 3in and made to suit the factory exhaust behind it. Unlike the full package in this range, it stops at the cats and joins back to the standard rear, so it's the engine-end upgrade for owners keeping their factory muffler and tips. The listing specifies right-hand-drive fitment.

What does a headers-and-cats section change?

This section swaps the cast factory manifolds for tubular headers and supplies a matching 3in cat section, then hands back to the standard exhaust. The trade-off is scope: you change the front of the system where the headers and cats sit, while the factory rear and its appearance stay. We publish no power or sound data, so we describe it only as a 3in headers-and-cats section to suit the factory exhaust — a front-of-system 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, right-hand-drive only. Fitment listings can be imperfect, so confirm your exact variant and that your car is the RHD configuration with the workshop before ordering. Recommended retail is $2,616.50.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits headers-and-cats sections like this in-house across the Illawarra. Because it mates to the factory rear, we check the headers at the heads, fit the cat section, then confirm the join to the original exhaust seals and hangs correctly. Send your Mustang's build and we'll confirm the fitment.
