Kooks Long Tube Headers - 04-06 GTO -
|
 |
|
Since 1962, Kooks has had the reputation of making the highest quality and best performing headers in the industry. Their Long Tube Headers for the 2004-2006 GTO uphold that reputation. Dyno gains of over 30hp have been reported and the exhaust note is utter muscle car music to your ears.
Primaries are manufactured from 1 3/4" mandrel bent T-304 stainless steel. With 3/8" flanges and 3" collectors, Kooks also offers a 1 7/8” primaries option for those with ported heads, cam and/or forced induction looking for the extra flow of a larger primary tube. For racing and off road applications only. Not legal for sale or use in the state of California, nor in states which have adopted California emissions standards. Check your local laws for emmisions regulations.
NOTE: Proper engine tuning may be required to ensure that the headers are properly adapted to your car.
