Header Reducers

Your headers end in one size, and the rest of your exhaust is a different size. Looks like you need some header reducers!

Since lap joints are easier to deal with than butt joints, it's ideal to have the outside diameter of the pipe coming off the collectors fit within the inside diameter of the exhaust pipe. Header reducers (sometimes called collector reducers) usually have a flange on one end, to connect to the header, and the other end is made to slip fit into your exhaust system. From there, it's a simple matter to clamp the joint together, or simply weld it.

Summit Racing Equipment makes it easy to find the reducer you need. You can filter the results below by collector diameter, outlet diameter, and even material and finish! If you need an exhaust sensor bung, you can filter those out, too.

If you need to change pipe sizes further downstream, Summit also carries exhaust pipe adapters and reducers to help you assemble the perfect custom system. For more information and advice on exhaust component sizing, check out this article and video on our blog.
