collector pipe gasket

They arent to bad on price depends where you buy them from. Yes you might not have leaks now but it will leak eventually these wont. To me money well spent. Plus think of this you ever need to drop the exhaust instead of 6 bolts and gaskets to worry about its just twonuts and the band thats removed, plus you can place the band nut anywhere for ease of removal or install can't do the same with header flanges.
