Show original supplier description
The Kooks 2-1/2" Competition Only H-Pipe is engineered for enhanced exhaust flow in 2005-2010 Ford Mustang GT 4.6L 3V vehicles. Crafted from durable 16-gauge 304 stainless steel, this H-pipe offers superior corrosion resistance and longevity. It features a ball and socket connection type, designed to mate seamlessly with Kooks Headers that have 2-1/2" collectors. This specific H-pipe is designated as "Competition Only" and "Off-Road Race Only," indicating it is not intended for street use and does not include catalytic converters. Installation requires Kooks Headers with 2-1/2" collectors. The H-pipe includes its own set of clamps for its connection, but the 2-1/2" outlet is designed to connect to the factory exhaust system, re-using the original clamps, which are not supplied with this product. This H-pipe is built to order in North Carolina, with an estimated shipping window of 4-6 weeks.
