We Will Price Match on These Headers!

Complete Bolt In Header System with Catted Crossover!

These 304 stainless steel long tube headers are for the 2007-2008 Ford Mustang Shelby GT500 with the 5.4L Supercharged V8. Kooks builds all of their products to the highest standard, and these are possibly the best headers you can buy for your GT500. This complete system feature 1 3/4" primaries, and 3" collectors with O2 Bugs welded in (both on the primary and collector). The system also includes Kooks 3" X-pipe Crossover that include high flow metallic catalytic converters. This system will bolt right up to your factory exhaust! Both are made of stainless steel and engineered to the same high standard as Kooks other products!
