Doug Thorley Headers

Awesome sound but needed modification

The bad: the crossover pipe didn't line up correctly on my 2008 Silverado 5.3. The exhaust shop had to cut, bend and splice to get it to work. Mine is lifted (suspension and body), so that may be the reason for it. Also, no gaskets included. The good: everything else is good. These are thick and heavy. The description says ceramic coated and the part # is for the chrome version... they are chrome (nice!). Sound is amazing with Magnaflow Performance series 24" (catless)! Very happy customer!
