2004-2006 GTO Parts & Accessories - Exhaust & Headers

Kooks Long Tube Headers 1 7/8"x 3" - 2005-2006 LS2 GTO


These 304 stainless steel long tube headers are for the 2005-2006 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.

To connect your new header system to your factory/aftermarket catback exhaust, you can also select either Kooks 3" Off Road Mid-Pipes, or their 3" Catted Mid-Pipes that include metallic catalytic converters.
