Lightweight stainless tubing

Do you want to save some weight from your race car that demands high exhaust flow ability, but don’t want to spend big money on exotic exhaust materials? We have the solution – our light weight, thin walled stainless tubing produced in house at Martelius.

The larger bore your exhaust, the more material you have and the more weight you carry under the car. More so, when going 4″ and beyond in diameter, it becomes increasingly difficult to find mass produced tubing material in even remotely racing friendly wall thicknesses.

We saw the need and made the investment of purchasing a fully automatic tube seam welding TIG robot, which we further modified to be able to produce stainless tubing from 3″ (76 mm) diameter upwards.

Currently we produce 3″ – 3.5″ – 4″ – 4.5″ – 5″ outer diameters with 1.0 mm (0.039″) and 0.8 mm (0.031″) wall thickness. Standard length is 75cm (29.5″). Custom diameters are available on request, send an inquiry for a quote.

For the bend sections we recommend our tight radius, 1.5 mm wall bends. With the slightly sturdier material the bend section remains rigid. The tight radius maintains low weight with short bend arcs. Another alternative is to pie-cut and weld the bends from the straight tubing lengths.
