Kooks Long Tube Headers 1 7/8"x 3" - 2004 LS1 GTO


These 304 stainless steel long tube headers are for the 2004 Pontiac GTO. Kooks builds all of their products to the highest standard, and these are possibly the best headers you can buy for your GTO. They feature 1 7/8" primaries, and 3" collectors with O2 Bugs welded in. With a proper tune at a dyno shop, or SLP's Diablosport Tuner, these headers are good for 20-35HP depending on the vehicle.
