TUBULAR MANIFOLDS

Exhaust manifolds, or headers, together with precision fabricated merge collectors are the heart of optimised exhaust systems. Successful management of gas flow begins with correctly pulsed manifolds and craftsmen formed merge collectors.

 

Our expertise. Our guidance. Your choice

An Alunox bespoke manifold begins with dialogue. The customers choice of metal, our advice on noise levels, collector design, slip joints and brackets, how to manage expansion, the potential for engine twist and discussion on all the parameters that make a precision fabricated manifold. We provide our professional guidance but ultimately the customer chooses.

 

Longevity

Choosing the right metal, the correct tube OD, the optimum wall thickness and keeping the number of welds to a minimum all help to prolong the life of a manifold. Choosing the right metal and grade becomes a critical decision if a turbo is installed e.g., Stainless Steel, Titanium or Inconel?

 

More power, managed heat & reduced noise

Alunox can work from engine builder’s specifications, customer’s designs, an OEM manifold or to our design given the limits of the engine bay. We fabricate around the restrictions ensuring that optimum power is delivered, and heat and noise come within prescribed limits.

 

Power and efficiency

Our aim is to optimise the power of the engine with equal length primaries and merge collectors that successfully manage the exhaust pulses of each engine. We only use TIG welding, gas purge all welded tubes and precisely swage slip joints as they enter the merge collector.

 

Full fitment service

To meet customers exact needs all systems fitted to vehicles in our workshop include adjustments after firing the engine.

 

Our guarantee. Your reassurance

Any system or part supplied by Alunox is warranted to the Original Purchaser to be free from defects in materials and workmanship.
