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 mild steel 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 vehicle’s rear axle simply by measuring, cutting, and welding the bend sections as required.

Welded Two-Chamber Mufflers Included for That Classic Sound

Our mild steel universal dual exhaust pipe kit utilizes 2-1/4-inch exhaust tubing and ships with our matching two-chamber welded steel mufflers. These mufflers feature an offset inlet with center outlet design and have a case dimension of 13-inches long, 9-3/4-inches wide, and 4-inches thick. Including the inlet/outlet bushings these mufflers are 19-inches long. These welded two-chamber performance mufflers provide that great classic deep aggressive exhaust note we all love while minimizing interior drone that can ruin your road trip. The twin baffle design creates a scavenging effect to help pull the exhaust through the muffler, increasing horsepower and torque. Constructed of 16-gauge steel, the case and internal steel baffles are full welded, meaning there is no internal packing material to burn up or blow out, so your exhaust sounds the same on day 1 as it does many years down the road. You can also find exhaust installation accessories including hangers and exhaust tips on our site.

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.

Overall Assessment

Customers find our exhaust kit an economical and high-quality solution for their various projects. Many have successfully installed the kit on models ranging from the '30s Hotrod to the F100 series. Some commend the kit's versatility as it comes with a generous selection of parts, often leaving extras even after complete setup. Customers recommend the kit as it's notably less expensive than building an exhaust system from scratch. The thick, sturdy, easy-to-weld, and durable material quality of the pipes is frequently praised. However, some customers found the exhaust sound slightly louder and the variety of bends could be improved. Nevertheless, customers overwhelmingly confirm they would buy this product again for future projects.

I will buy this kit again

I recently bought a 29 Model A Roadster garage find that had not been driven since the fall of 1991. Flat spotted tires, rusty exhaust, steering issues, wiring issues, new column, safety issues, on and on . Old school hot rod that needed some love. I was able to weld up a new exhaust and had the roadster off the lift in just a cpl. of hours. It came with way more bends and material than I needed. Got enough left over to do most of the exhaust on my 29 sedan build.

Needs a better selection of bends to make it more universal

Used this to fabricate an exhaust on a LS 52 chevy sedan. U tubes were not wide enough to clear axle sufficiently. 2 U tubes should be substituted for 4 20 degree bends. Straight pipes should be flared on both ends so they could be used for short sections if needed.
