anit-sieze on for the header bolts. I didn't get new gaskets or stage 8 bolts the ones that came with mine were fine. I reused the stock gasket aswell no leaks. I retorqued the bolts about a week after installed them then haven't touched them since then its been almost a year now.
LOL Sorry dude. Well to get back on track, are you gonna get it all welded up and installed at a shop? If not you will want some quality exhaust clamps. Like the Walkers or Torcas. Moes or Airram has them.
