SKU #: Bul-85302 Bully Dog Exhaust Manifold for 2004-07 Detroit Series 60

These manifolds are the fastest flowing pieces available for the Series 60 14.0L Detroit EGR engines. You will notice quicker turbo spool and higher power output and economy from your engine. You can expect more horsepower and improved mileage with the addition of this manifold. These improvements all result from a more efficient design, a high quality manufacturing process, and a detail oriented finishing process.

Superior design and manufacturing:
The manifold was designed by cutting corners; wait, not like you think. Like this: we took all the sharp corners in the stock design and the competitions designs and totally smoothed them out, creating a design that flows 18% better as tested on a flow bench. The manifold itself is cast using a high quality molybdenum-steel blend, and then hand ported and polished, and finally topped with an ultra smooth ceramic coating. The ceramic coating will ensure smooth, fast flowing air and excellent thermal properties. Temperatures radiating off of this manifold are 300 degrees less than the competition.

Why would you need such a manifold:

• High performance applications: if you add a larger turbo then you will need the air flow to support that. You may also need it if you're doing some high hp tuning or you risk not reaching your full potential.

• Customization: every trucker takes pride in their truck, just like they take pride in their jobs. This manifold will truly show how much you care for your truck by adding a touch of performance, reliability, and shine.

• Low risk performance: if you're just looking for small improvements in power or economy this product might suit your needs as your only performance upgrade.

• OEM manifold fails: some OEM manifolds have been known to fail by cracking or leaking, replace it with a manifold that won't.

Be sure to double check this part number with your stock OEM part number. If they do not match, give us a call.
