Doug Thorley Headers Reviews


5.3 2013 Silverado

I play proball and my buddy on my team has the doug thorley longtubes on his 09 6.2 silverado and he talked about it helping more with Power than even his Tuner. He wasn't lying. As far as installation goes. Just take your time and do it right. Take a day and do it right and it's not bad at all. Once you get the stock headers off putting the new ones on is not bad. Use PB blaster to loosen old headers. Much easier after

Flowmaster Scavenger Series Elite Headers Reviews


Very satisfied

Reviewed By Cody F (Reading, PA) Reviewed for a 2012 Dodge Challenger —4/13/2016 6:25 AM

The headers arrived in good shape. Welds were solid. No dents or dings anywhere. I recommend reusing factory gaskets or get new gaskets from a dodge dealer because these gaskets do not have a heat shield for your valve covers/wiring.
