I beg to differ. Mine are coated, don't leak at all...and are 2 piece just like ZZP's. Only difference is slip fit vs. my 2 bolts (front header to crossover). If you don't want to take the time to have them welded up then they aren't a good buy and they used to be awesome budget headers...but time moved on and now SD headers are where its at. Get them.
mine are coated too... and i followed the welding instructions by bluegtp
