Porsche 911 991.1 Turbo Manifolds

Out Of Stock (13 In Production)

These 44MM bore size manifolds are ideal for the 911 991.1 Porsche Turbo in order to enhance sound and flows; and are a flagship Topgear unique product, with a fantastic appearance and proven gains in power and throttle response. With a sleek brushed finish and TIG welded to perfection from 100% 304 grade stainless steel, we are certain that you will be delighted with the result. The manifolds are a strict upgrade from the OEM and are ideal as either a direct replacement, aftermarket upgrade or fitted in conjunction with one of our exhaust systems for 911 991.1 Turbo. The increased bore size translates to more free-flowing engine gases, leading to performance gains in terms of both HP and torque. Direct fit part for all first generation 991 Turbo fitments, 2013-2016, including Turbo, Turbo S and Turbo Cabriolet models. Bolt on replacement with no cutting or welding required, however re-use of OEM factory gaskets is required. 

Unlike the 996 and 997 Turbo, the 991 headers are very restrictive and the clam shell design prohibits the turbos from spooling up quickly. These beautiful tubular stainless steel headers solve this problem through superior design and a sleek 3-1 collector.
