Not sold as GSF but i ran OBX without heat for around 2 years and probably would be still running them if i had not grounded them on 3 seperate occasions,,,the 3rd grounding just proved to be too much for them and probably would have been too much for any brand of headers.

My car runs over 400 bhp at wheels and while i ran them they were exposed to some extreme conditions several times(roll'n'road sessions) dyno days) and always held up perfectly!

Fitment issues they did have and i thoroughly checked/cleaned inside before i installed.....

These are my personal honest experiences with OBX headers.
