3,5" Straight oval tube – 60.5 × 104.9mm (1 meter)

Straight oval tube – 60.5x104.9mm (1 meter)

This oval exhaust tube is manufactured from SS304 stainless steel and designed for applications where space is limited but high flow and professional quality are still required. With its low profile and wide shape, the tube allows efficient exhaust routing through tight tunnels, under rear axles, or along the underbody where a traditional round tube cannot be used.

The 60.5x104.9mm cross-section provides a flow area that in practice rounds to approximately 81mm (3.2") round. This places the tube firmly in the performance segment and makes it suitable for engine setups in the 650–700hp range with a single exhaust system, depending on overall system design, length, bends, and component selection. Compared to a true 89mm (3.5") round tube, capacity is lower, but clearly above traditional 76mm solutions.

The oval shape offers a clear advantage in installations where maximum flow must be combined with minimal vertical clearance. For this reason, this type of tube is often classified as 89mm (3.5") nominal in performance systems, even though the actual flow equivalent is closer to 81mm round.

The tube is supplied in a straight 1-meter length and is intended for custom exhaust systems where precise fitting and welding are required. The SS304 material ensures high corrosion resistance, excellent weldability, and long service life, even under high temperatures and demanding conditions.
