Doug Thorley Headers Reviews


Excellent!

Reviewed By Brad S (Franklin, OH) Reviewed for a 2001 GMC Sierra —11/27/2006 8:39 PM

These headers really helped wake up the bottom end of my truck. Construction and finish are excellent. These are probably the best header out there for a 4x4 truck that needs all the low end torque they can get. The 310Y is a long tube headers and gives you the best power band, better than the newer midlength model.
