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.
