Collection: Oval Exhaust Tubing

Browse Proflow oval exhaust tubing and fabrication components for custom exhaust routing where vertical space is limited. The range includes straight stainless steel tubing, oval-to-round transition adapters, pre-welded bends and loose pie-cut sets in selected 3-inch, 3.5-inch and 4-inch nominal sizes.

Choose by dimensions and routing

• Width and height: Check the actual oval dimensions against the available space beneath the vehicle. Do not rely on nominal size alone.
• Length: Confirm the supplied length in each listing. Straight tubing lengths vary, including 1-metre and 920 mm options.
• Bend angle and orientation: Match the required angle and horizontal or vertical bend orientation to your planned exhaust route.
• Component type: Distinguish between pre-welded bends and loose pie-cut sets that require assembly and welding.
• Transitions: Check both the oval dimensions and round connection size when selecting an oval-to-round adapter.
• Material and fit-up: Verify the stainless steel grade, wall thickness and joining requirements in the individual product specifications.

Plan clearance around the chassis, driveline and other components, allowing for exhaust movement and heat. Have your fabricator assess the complete system's dimensions and flow requirements rather than assuming nominal oval and round sizes provide identical internal flow area.
