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.

Reviewed By Kevin B (Dracut, MA) Reviewed for a 2008 Chevy Silverado —11/13/2014 6:46 PM

I had a few broken manifold bolts and a bad manifold, so I upgraded to these. Very pleased with the look and quality. I wish they were a little less expensive. Install went well with the exception of the broken bolts that had to be removed.

The reason I bought these and the only reason I bought these is because they are California exempt the sticker supplied with the supplied with the header is just a plain white piece of paper it's not going to withstand the test of time it's gonna rub off I'm not gonna be able to get smog all other manufacturers use something like a metal sticker so I call FlowMaster advise them of my concern asked for a replacement for her like a stick inside the glove compartment of my car and they refused to give it to me so far one guy wanted for her to tell me just going to write it down on a piece of paper I double checked
