ALUMINUM MUFFLERS
Our aluminum mufflers have a unique sound. The tone is low, and doesn't rasp at high-rpm. The mufflers actually muffle the exhaust (to your tastes) and can save a substantial amount of weight in the process. Ceramic packing material ensures lifelong performance and quality sound, while our CNC billet end caps ensure longevity under the harshest conditions, and a unique look.
Stainless and titanium mufflers are available upon request, please contact us for pricing.
Listed below are some of the more popular sizes of our mufflers and the corresponding prices. There are many options available, the benefit of custom is being able to tailor our product to your needs. If you are not building an aluminum exhaust, we can weld v-band flanges on the mufflers before shipping, and send along matching steel flanges and clampsto install on your exhaust.
A typical 3" inlet/outlet muffler with a 6" OD weighs less than 7 lbs. Compare this to other designs in stainless that actually work to reduce sound levels and combat drone, at 30-35lbs each.

From broken snowmobile crank cases to cracked marine manifolds, repairs can save money over replacement in some cases. For those items that are rare, or discontinued, it may be the only option.


We can make you an exhaust out of mild steel, aluminum, stainless steel, inconel, or even titanium. A complete exhaust can be made from head flange to tail pipe, or just a downpipe for your turbo car. Exhausts are available in sizes from 2"-6" in any material you may require. Custom headers for swap cars or unique projects can be a viable solution.
Every stainless exhaust piece and system is purged with inert gas so that the welds are as strong as possible. Doing this does cost more, and makes the process slower, but it ensures longevity and consequently, stainless systems built by Unobtainium Welding will outlast most of the vehicles they are installed on.

What kind of exhaust is best?
For most street and performance exhaust, 304 stainless steel is an excellent choice. It has good corrosion resistance and is able to withstand an occasional scrape. Most stainless exhaust will outlast the vehicle.
For those who have to have the lightest possible exhaust, aluminum works great at 1/3 the weight of stainless with great corrosion resistance as well. Aluminum can take enough heat to last a very long time. It is a softer metal, so scraping can cause damage easily.
If there is an application that must have both very light and high heat tolerances, then 321 stainless or titanium are the best choices. 321 is a special grade of stainless engineered for high-heat applications in aviation. Titanium is very strong, and scraping would not damage the tubing enough to worry about. It is very expensive, but is very strong and is more corrosion resistant than either aluminum or stainless.
