Burns Stainless Merge Collectors are extremely popular with NHRA racers and
NASCAR engine builders, and are widely used in IRL, ALMS, FIA-GT, and Trans-Am as well.

Custom engineered for each application using our proprietary X-design parametric exhaust design computer program, Burns Stainless Merge Collectors combine high flow and high velocity to increase and broaden an engine's torque curve all the way to the horsepower peak and beyond.

They feature the highest quality fabrication and welding,
and each is completely hand finished inside for proper flow.

For Drag Racing and similar applications where a tailpipe is not required, megaphones fitted with reverse cones are invariably the best option.  They make the the most horsepower, maintain the highest and smoothest torque curve, and, on well developed engine combinations with optimally short header tube lengths and a well chosen collector outlet diameter, offer the highest potential power past the peak without compromising the lower end of the power band.

Here are five of our most common merge collector configurations.
To specify collectors for your application, we need to determine 4 basic parameters.

1. Inlet Diameter - the outside diameter (OD) of your final header primary. That is, the OD of the tube that will slip into the collector.

2. Collector Outlet Diameter - determined by our X-design program.
There is no standard outlet size; each collector is based on the engine’s specs.

3. Outlet Style

Long or Short Transition, usually fitted to tailpipe setups, often with ~ 2” long tailpipe ring.


Megaphone, for maximum peak horsepower and power bandwidth, especially with reverse cone.


V-band flange, typically added to turbo collectors


Straight extension, frequently used with 4-2-1 header primary collectors


4. Final Outlet Diameter and Configuration

If yours is a tailpipe application, you will probably need a tailpipe ring.

If you select a megaphone, a reverse cone is highly recommended.

Each of these is available in 2, 3, 4, 5, and 6 into 1 configurations
5 into 1 and 6 into 1 collectors are special order items.
