Design Your Own Exhaust System with Our Complete Header Back Exhaust Kits

Many builders look at the exhaust portion of a project build with skepticism and disdain. It is normally one of those aspects of a project where you know it is going to entail delivering your project vehicle to an exhaust fabricator and having a complete header to tailpipe custom exhaust system built at great expense. It is even more fun when you do not own a truck and trailer to transport said vehicle yourself too! However, we are here to tell you that you can indeed fabricate your own custom exhaust right in your home garage or workshop with ease using one of our complete dual exhaust pipe kits we offer here at Speedway Motors. All it takes is a welder, something to measure and cut the piping with, and a little bit of exhaust pipe system routing forethought to accomplish.

Heavy Wall 16-Gauge Tubing for Easy Welding and Fabrication

We start by spec’ing .065-inch thick 16-gauge mild steel tubing for our mandrel bent exhaust pipe kits. This steel is easier to weld by far when compared to standard 18-gauge steel normally used for exhaust tubing. The thicker gauge material provides “forgiveness” when welding if your welding machine settings are not spot on, making it easier for novices with basic 110-volt MIG welders to weld up the perfect custom exhaust system. We provide four 46-inch lengths of straight pipe for the main exhaust pipe run along with four lengths of each bend type: 90-degree, 45-degree, and 180-degree U-bends. These bends allow you to fabricate the optimum dual exhaust system routing around crossmembers and over your rear axle simply by measuring, cutting, and welding the bend sections as required.

Just Add Mufflers and Hangers to Complete Your Exhaust

Our mild steel universal dual exhaust pipe kits are available with or without our welded steel 2-chamber performance mufflers. This kit utilizes 2-1/2-inch exhaust tubing and ships sans muffler assemblies so that you can choose the exact muffler to fit your chassis and desired sound and performance levels. You can find this 2.5" exhaust pipe kit with mufflers along with exhaust installation accessories including hangers and exhaust tips on our site. Be sure to have a quick read of our muffler buyer’s guide over on our Toolbox page to aid in choosing the right muffler for your project.

Extra Exhaust Tubing is Just a Call or Click Away

Sometimes we measure twice, cut once, then cut again, and still come up with the short end of the stick, or in this case, exhaust pipe. Have no fear, Speedway Motors offers individual replacement angle tubing and additional lengths of straight tubing in case you have a project with a long wheelbase like a station wagon, panel van, or other unique scenario. If you know what you need you can order these along with your hot rod DIY exhaust kit, otherwise, know these parts are ready to order to get you fixed back up and your exhaust project finished in no time if you make a mistake with your exhaust fabrication.
