1 7/8″ GTO Header System
Free Shipping!
ARH GTO systems are here to make a statement. Manufactured in 304 S/S, these headers are available from New Era Performance with 1 7/8" primaries. Merge collectors with scavenger spikes are standard along with our bullet proof high flow metallic substrate cats. Systems are available as a direct built-in for all 2004-2006 models or choose the 3" X-Pipe option. Expect outstanding performance gains throughout the RPM range and a fit and finish second to none.
Don't compromise on fitment and quality in your GTO. This is the only system we use!
Please select the following from the drop down menu:
- 200 cell metallic substrate cats
- Direct-fit or X-pipe
- Year of vehicle (LS1 / LS2)
** Direct fit bolts directly to stock mid pipes. With these vehicles aging, select the x-pipe option for a bolt and gasket-free installation. The x-pipe system requires you to cut part of the exhaust, so the x-pipe can slip over and clamp to it. We highly suggest this system.
