This pair of high flow, 200 Cell Sports Cats add +12 to +15 HP and a slightly sportier note to any 911 997 Carrera (first generation). Gaskets and bolts are included with the package, making for a fuss-free and swift direct fit replacement part. Four holes have been put into place for lambda sensors. The part is 100% 304 grade stainless steel, TIG welded, mandrel bent and boasts CNC machined flanges. Crafted in the UK, this part will fit like a glove, sound great and you'll immediately feel the power gain over the standard Porsche 400 cell catalytic converters. The parts provided are 100% stainless steel, weigh just 3KG each and fit all 997.1 Carrera variants (2005-2007 aka pre-PDK) including Targa. The pair are a direct fit replacement and are fitted to the same location as the OE (original equipment) parts.
