Out of the box these seem like very high quality. They have very thick flanges and the wall thickness of the tubing seems more than adequate. I installed the headers on an LS swapped c1500 and the only figment issues I had were that I had to re-route my hydraulic clutch line and I had to remove the drivers side tin heat shield. Factory straight boot plug wires will interfere with header tubes on 2-3 of the cylinders so wires with angled boots are a necessity. My only complaint about the headers is that I wish the v-bands were stepped to ensure a concentric fit. Not a huge deal but it would make fitting up the rest of the exhaust a little easier.
Was excited when product showed up. Looked great and nice welds. But when I put them on they ride real close to the block and it sent the left side right into the front driveshaft so I don’t think they will work on 4x4, but could’ve made work on 2wd. So was bummed that I had to return. So why am I giving a 5 star?? Well because when I called in to Pro, I was treated excellent. They didn’t hassle me and didn’t tell me I was doing something wrong with the install or it was my fault. Very very happy with the customer service. They took the return and paid for the shipping. For this reason alone I hope to buy more products from them on the next LS swap. A lot of aftermarket company’s can learn from this. Good customer service goes along way and will come back to you in the long run!!! Thanks Pro Performance!!!!!!!!
Awesome product and thank you for the patience in answering all my questions! Will buy again, great customer service!
