Is anyone currently using these headers? I have been fighting exhaust leaks around the driverside header, crossover leaks for a while and wasting time and money. The ATR driverside header ball flange is warped(oval) and the new SS crossover is a tight fit underneath and it leaks horribly at the flange. I put in an order today for a stock driverside header from Seturbo, but I'm thinking about just getting an entirely new set from ArizonaGN. The mild steel looks like they won't leak and I will never have to worry about warping another ball flange again. Just wondering if anyone has them.
