Premium 90&deg Titanium long elbow for DIY exhaust systems, downpipes and more - Various Sizes

BOOST Products high Quality Titanium mandrel bend in Grade 2

BOOST Products ultralight titanium pipes, bends, flexible joints and exhaust accessories are made of high quality Grade 2 titanium. Unlike other manufacturers, BOOST products focuses on high quality (grade standard). Especially for titanium products in exhaust systems, it is absolutely necessary to use at least Grade 2 quality standard.

Due to its special material properties, titanium is an ideal material for the construction of exhaust systems, downpipes, or charge air pipes in motorsports. A very low weight combined with high tensile strength allows the use of lower material thicknesses, so the metal naturally weighs less than steel and in many ways just as robust. It is not unusual for a complete titanium exhaust system to weigh less than 7lbs.

BOOST products titanium pipes are available in 1m length and multiple bend radii. Also available are various brackets and flex exhaust bellows in titanium.

How hard is it to weld titanium?

Titanium is one of the harder metals to work with when it comes to welding. You'll need to TIG weld here and a 100% Argon purge is recommended to avoid atmospheric contamination. This is important because if not done properly, this causes cracking and ends up failing sometimes easier than steel. In our experience, fabricators say you should use ERTi-2 filler rod for any Grade 2 titanium.

Do I really save that much in weight?

It is actually quite considerable the amount of weight saved when it comes to titanium vs. steel. On average, titanium can weight about 45% less than their 304/316 stainless steel counterparts. Our 4 inch 90&deg only weighs about 2 pounds, so you can imagine the overall savings when you build out an entire exhaust system.

Grade 2 vs Grade 5 titanium

Grade 2 titanium is the type you see the most when it comes to commercial sales. They are found in exhausts, piping and even some checmical equipment. For those wanting high quality metal that is rust resistant and offers plenty of tensile strength, you'll see most using Grade 2. Grade 5 is more for aerospace, aircraft turbines, high strength valves and other complex systems. They have a much higher tensile strength but is not for the casual DIYer. They are extremely difficult to weld with, does not form well and are extremely difficult to machine.

Some things to consider

We use grade 2 titanium for our line of titanium piping products. Grade 2 is the most commonly commercialized version of the types of titanium we see on the market. It's the main industry go-to standard for exhausts, downpipes or intake plumping.

While the result could be visually stunning, we recommend you have experience as a fabricator before undertaking a titanium welding project. They are not the easiest metal to work with - nor is it the cheapest. They are less forgiving when it comes to how it's welded, they can crack easier than steel if the welds are not done properly.

The discoloration after heat is put through it is normal and often the reason some even use titanium.

Titanium has a different resonance than steel, so the sound will be quite different if building an exhaust system
