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.
