The tube is made from the highest quality materials on offer in Australian. Its made to Australian standards and will easily cope with the extreme conditions of an exhaust. The tube can be easily formed and bent to any requires necessary. The 304 stainless steel has a 320 grit buff finish which is a very fine sand paper look which can still be seen. The tube could be polished into a mirror type look with so elbow grease. The tube comes in 6 metre lengths and is cut down into 1 metre length to be sent out. Larger lengths can be ordered but will need to be shipped with a courier. Contact us for cost. The tube is well suited for car, bike, boat exhausts as well as many others. There are a bunch of ways to weld the tube together but we would highly recommend them to be MIG or TIG welded together to receive the best possible finish. We also sell double couplers & clamps to join tube to bends or other parts of the exhaust for the customer who may not have welding facilities available.

Buy a 304 Stainless Steel Tube from Australia's Best Exhaust Specialists

If you're an experienced seller or familiar with cars, you'll already know that different alloys are suitable for different parts, models, or setups. If you're looking for something light, easily available, highly malleable, and affordable, mild steel is the finest choice. For custom cars, on the other hand, many customers prefer something more durable and resistant to rust and corrosion, which is what makes 304 stainless steel the perfect middle ground.


ECS Exhaust 304 Stainless Steel Tubes

Our 304 stainless steel tubes come in several finishes depending on your aesthetic preferences or needs, and you can filter your options according to brand, price, wall thickness, and external diameter.

While you're browsing, check out any other parts you might need other than our 304 stainless steel tube, such as our adapters, reducers, and mandrel bends. If you're unsure what sort of alloy best suits the climates you'll be driving through most often, get in touch with one of our engineers for advice and recommendations.

316 Stainless Steel Tubing Expertly Made Right Here in Australia

If you're restocking on car parts such as the 316 stainless steel tubing, especially if you're in a hurry, you might look for the most affordable, easy option, which is often importing those parts cheaply. However, past a certain threshold, those low prices can be a red flag. How can you verify the quality of the manufacturer? How secure is their shipping? How quickly will your order arrive? The last thing you need as an auto parts seller is to place a massive order for mufflers with an overseas business that never arrives; accountability is much harder to act on in those cases. With ECS Exhaust (leading car exhaust parts online supplier), those concerns are gone.

316 Stainless Steel and Its Properties

This grade of stainless steel is the second most popular after 304, and they're very similar. The difference comes in their concentrations of the element molybdenum. The higher molybdenum percentage in 316 gives it far more longevity and rust resistance than 304, and it's especially useful for drivers near the sea, as saline climates will corrode 304 extremely quickly. If you live near the ocean (and that's not so unlikely here in Australia), your best bet might be some sturdy 316 stainless steel tubing.

Q - What grades of stainless steel do you stock?
A - We offer 3x different grades of stainless steel. Our straight tube comes in 304 or 316 stainless. Our stainless steam straight pipe is a 304 grade.
Stainless steel mandrel bends come in 201, 304 & 316 stainless (different sizes and angles available depending on the grade), our catalytic converters are in a 409 stainless steel.


Q - What is the difference between TUBE and PIPE?
A - The difference between tube and pipe lies in the way it is measured. Pipe uses a nominal bore measurement, which utilises the inside diametre as well as the schedule (wall thickness). Tube is measured OD - outside diametre.


Q - What is the best material to use for turbo manifolds?
A - When fabricating turbo manifolds, steam pipe has a thicker wall that allows it to cope with the extreme heat exposure. We offer a range of steam products - mild and stainless bends as well as straight pipe lengths.


Q - What does CLR stand for?
A - Centre Line Radius is the distance from the center of curvature to the centerline (axis) of the pipe, expressed as a number multiplied by the pipe or tube size. 


Q - Can you use petrol cats (catalytic converters) on diesel engines?
A - The cells of catalytic converters have a washcoated surface that makes them unsuitable for use in diesel engines.

Q - What are your size and angle ranges in mandrel bends?
A - We stock a large range of mandrel bends to suit most applications, including car, boat, bike, food grade or for commercial applications.

Bends are available in 3 types of material - mild steel, stainless steel and aluminium.

Stainless steel bends start as small as 1" and go through to 4" - mild steel bends start in 1 1/4" and go up to 4", and alloy bends start at 2" and go to 3 1/2".

Angle ranges vary depending on the material, our mild steel bends have the largest angle range available: 25, 30, 45, 60, 75, 90,125 & 180deg bends in most sizes (from 3.5" up we have just 45 & 90deg bends).

Our stainless steel comes in a 'long leg' and 'short leg' option depending on the grade of stainless you're after. Our long leg bends have much the same range of angles available as the mild steel bends offer. The short leg bends are sold in 45, 90 & some in 180deg.
