Balanced exhaust flow for more power and lower EGT’s!

You may not know it, but the factory driver’s side exhaust manifold is pinched down to allow for steering shaft clearance, which actually isn’t required. As a result, this manifold only flows 80% of the passenger side. BD’s Full Bore exhaust manifold restores exhaust flow balance, improving power and reducing EGT. Made from high-silicon ductile iron, the Full Bore is a direct, bolt-in replacement for the factory manifold and is even drilled and tapped to accept the most popular EGT probes.

Aluminized down pipes, cat-back and complete exhaust systems for earlier diesel trucks. Featuring large diameter, mandrel-bent tubing, BD's aluminized systems are a great performance value.
1994-99 BD has 2 kits to choose from! The most popular kit is the rear portion, which replaces the stock 3" system from the cat to the tail pipe. Our high flow 4" Big Mac Muffler slips onto the 4" mandrel bent over the axle pipe and is finished with a chrome tail pipe extension. Sounds tough but classic and improves the turbo response.

Easily installed by the back yard mechanic!

We also have the front portion of the system from the turbo to the Cat in 4" pipe. When you combine both kits you will open the system for optimum turbo performance. This kit does require some welding to fit it on the cat.

Dodge Ram's 89' to 93'

Our 3.5" over- the- axle pipe and low restriction muffler is a 100% improvement over the stock exhaust system. If you have a 4x4 we also have an intermediate pipe that has mandrel bends to route around the transfer case for smooth quick exhaust flow.

For those who want to give their Diesel pick-up the BIG BAD TRUCK look, BD's new Stack Exhaust Kits feature 5-inch 409 Stainless Steel tubing with a single inlet / dual outlet design that incorporates an internal plate to ensure equal exhaust flow out of both polished 304 Stainless Steel stacks. Comes with all clamps and hardware.
When you know the difference, you'll choose BD!
This universal kit will couple to most
aftermarket turbo downpipes but if no
performance downpipe is installed,
BD has 409 stainless downpipe kits
available to complete the installation.
