3/4 Aluminum Scalloped Tube - 11in.

The 3/4 Aluminum Scalloped Tube - 11in. from QUICKCAR RACING PRODUCTS is a precision-engineered intake or exhaust manifold component designed for engine builders and race car fabricators seeking weight reduction without sacrificing structural integrity. This scalloped tube design serves as a critical element in custom intake manifold assemblies, turbo piping systems, or exhaust headers where space is limited and airflow optimization is essential. Whether you're building a bracket racer, circle track competitor, or street performance engine, this tube delivers the durability and precision fit that serious enthusiasts demand.

Constructed from lightweight aluminum alloy, the 3/4-inch diameter tube provides excellent strength-to-weight ratio while resisting corrosion in high-temperature engine environments. The scalloped profile—a series of contoured indentations along the tube wall—increases surface area for improved heat dissipation and reduces overall weight without compromising hoop strength or burst pressure tolerance. At just 0.66 pounds and measuring 11 inches in length, this component integrates seamlessly into compact engine bays where every ounce and inch matters. The precision 1.6 x 1.3 x 12.6-inch envelope ensures accurate fitment in OEM and aftermarket manifold kits, while the aluminum construction simplifies welding, porting, and custom fabrication work.

This tube is ideal for engine builders, race fabricators, and performance shops installing custom intake or exhaust systems on modified engines where stock components fall short. It pairs naturally with carburetor spacers, aftermarket cylinder head port work, and turbocharger inlet piping applications. Installation requires basic welding skills and fitment to your specific manifold design; the 3/4-inch diameter accommodates most intake flow rates from 150 to 350+ horsepower naturally aspirated engines. Always verify bore size and port spacing on your application before ordering, and plan adequate clearance around ignition components and valve cover assemblies.
