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 stainless-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 Stainless-Steel Tubing for Easy Welding and Fabrication

We start by spec’ing .065-inch thick 16-gauge stainless-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.

Just Add Mufflers and Hangers to Complete Your Exhaust

Our stainless-steel universal dual exhaust pipe 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. Be sure to have a quick read of our over on our Toolbox page to aid in choosing the right for your project. You can also find exhaust installation accessories including and 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.

Excellent quality product Rated by Gumby on October 13, 2015

Summary: I got this tubing kit quickly from Speedway. The bends are all bagged in a big box and the straight pieces are in a long box of their own. The finish on them is excellent, especially on the unbent tubing. It's as close as polished as I've seen and I wasn't really expecting that. I've cut up several of the bends to build my system and they're not deformed (ovaled) and the outside radius walls of them are still plenty thick to weld and not worry about cracking or anything. I priced 304 stainless 2.5" kits from every website I could find it and this was by far the cheapest. Plus the number of bends and tubing you get is is more than what I could find elsewhere. I probably have enough to do another single system after installing this as dual exhaust on my 71 GMC. Keep in mind this is a legit 304 SS exhaust kit, not 409 which honestly I would rather use aluminized (which I wish Speedway carried IMO). The flared ends are sized well and slip together easily, but without too much slop that would be a pain to clamp. Note, this is a raw tubing kit which definitely takes some fabrication to install into a vehicle. I managed to run both sides all the way to the mufflers (under the bed) without having to cut up many bends, but building the tailpipes takes a little work. This kit has so many 45 and 90* bends though you definitely won't run out on any normal car or truck. I'd definitely recommend this over the raw steel kit since it's not at all coated and would likely rust out. This kit will likely outlast the rest of your vehicle.

Cons: No Smaller Kit Offering

Pros: Flared Ends Are Nice Good Price / Value More Than Enough For Job Nice Finish Packaged well The Bends Are Uniform

Yes, I recommend this product.
