These headers are available only via Special order or with a Group Buy. We are not stocking them.
1 5/8" Primaries flow into a 2 1/2" Collector. Made from mandrel bent 304 STAINLESS Steel material! This purchase is for a PAIR of headers (right/left).
Includes the EGR fitting and the O2 Sensor fittings.
Larger 1 3/4" primaries and a 3" collector is a $95.99 option for those engines making in excess of 500 HP. Call to custom order the larger size or state this request in the "Comments" section during checkout.
We offer these for the 2-valve or the 4-valve cylinder heads. They can be custom ordered to fit a MN12 with a engine swapped DOHC 4.6L also.
Uncork your 4.6L exhaust and let that V8 exhale with authority! The 3/4 length design will augment low end torque and provides plenty of room after the header for a smooth down tube and catalytic converters (if used).
Because these headers are significantly longer length than the factory manifolds, they require Oxygen sensors with longer leads. It is always a good idea to replace your O2 sensor at 60,000 mile internals as they gradually degrade over time. If needed, we can provide these long lead sensors for you. If you happen to have recently replaced your stock O2s then we also offer O2 extension harnesses to lengthen the leads.
2.5" diameter down tubes are also required to mate with our collector. We do not offer a mating down tube at this time, but any skilled local exhaust shop can bend these for you to mate with the remainder of your exhaust system. We do offer new 3-bolt header adapters with soft copper gaskets that you can use as the first part of the rest of your exhaust, as well as high flow catalytic converters in the 2.5" size at terrific pricing. Let us know if you would like either of these to use in your down tubes.
