Tech Tips

Stainless Headers Mfg., Inc. is a major supplier to fabrication shops as well as individuals who build their own headers. Even though Stainless Headers Mfg., Inc. is the premier builder of custom headers, a large part of our business is selling components to builders themselves. We thought we would pass along some of our header building experience to our customers. On this page you will find a custom header fabrication video series that we hope you will find helpful. Along with this video series, you will find a long list of custom header building resources, such as header design programs and articles, welding links, fabrication equipment and supplies and links to general shop equipment suppliers that we use. We hope you find this custom header fabrication information helpful.

Check out our header calculations page for general rules of thumb, and some basic equations for figuring out some starting points on header sizing, collector sizing, turbo charger selection, and more.

Check out some more information on that custom tip we did up for #GameOver for Finnegan’s Garage. Great looking, and better sounding replacement for those old teardrop tips. We are proud to supply Mike with stainless header materials on a great many of his builds, and all USA made products.

Custom tips like this are always special for our team, it’s a great way to pull of the leashes and let out some creative freedoms. This tip was inspired by some previously built Lamborghini & Ferrari tips, as well as the Pagani Zonda. Those prolific exhausts combined with the wonderfully crazy ideas in Mike’s head led to this beautiful piece.

Mike Finnegan of Finnegan's Garage came to us for a special project on his twin-turbo jet boat "Game Over". The previous downpipes and wastegate dumps weren't the look he wanted, but also weren't giving correct readings on his O2 sensors due to turbulent airflow, which was making tuning difficult. So, he drew up a quick sketch of a new exhaust tip he had in mind and came to us for an answer.

We were able to fabricate a badass tip as well as supply all the mandrel bends needed for him to redo the entire hot side of his turbo system.

We hand-fabricate custom projects to spec & design every single day for our customers, and this was certainly no exception. We operate in one-off parts such as Game Over's tip, but we also run batch parts, such as custom merge collectors for turbo snowmobiles, large scale muffler production for Ferrari and Porsche, and much more.
