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.

Overall Assessment

Customers consistently commend the product for its high quality and impressive practicality. They particularly appreciate the vast quantity of tubing provided, stating that it is sufficient for a complete dual system. Some remark positively on the ease of installation, highlighting how the system enhances the appearance of various vehicle models. The product's quality is frequently mentioned, with users noting the mild steel composition as a definite pro, though they advise painting to prevent rusting. A few customers suggest that the flares might be marginally larger, causing a slightly loose fit. Nevertheless, the overall consensus labels the product as a perfect, affordable solution for self-done exhaust systems.

Great deal!

Bought this kit in 2 1/2 inch mild steel for my '33 Ford tudor sedan. Wanted plain mild steel for better welding as I had the entire exhaust coated. Other stores offer only aluminized which I did not want. More than enough bends and straight pieces to run from the block hugger headers, over, under, around, and through the crossmember/trans mount. Also went up and over the differential and clear out the back past the gas tank cover. Everything welded nice and cut great on my chop saw. This is a great deal. Will do again on my '72 Jaguar lump. Looks absolutely great coated. Speedway never disappoints.

the straight pipe sections were larger than the bent pipe sections so the pieces did not fit well when pieced together using a mixture of bent sections and straight sections. I had to cut various pieces to make a dual side exhaust system for my 33 Ford street rod to come out just ahead of my rear wheels. My exhaust tips would fit on the smaller pieces in the kit (90 deg. and 45 deg.) but when I cut a straight pipe piece the length I needed the exhaust tip would not slide over the cut pipe. At least I was able to piece together what I wanted using only the bent sections. Now, when the weather breaks I'll test how well I like the looks and sound. Then I'll take it to a shop and have it redone to match what I have but in stainless steel.

The kit was pretty complete. I only had to buy two more U bends to complete a dual exhaust from header to tail pipe at the rear of the car.

I stumbled on this universal exhaust kit and have lots of options to run the dual exhaust. There are more parts than I will ever need to put a complete exhaust on a 1952 F1 sitting on an S10 4x4 chassis. It is a home conversion I am doing in my small shop in honor of my oldest brother. This conversion was his idea, but he didn't live long enough to do it. I was about 8 years old when he last drove it in 1971.
