Using these headers is quite straightforward. First, make sure you have the ISR Performance VQ Swap mounts as they're required for proper fitment. Before installation, check the headers for any damage during shipping. When installing, do some clearancing of the floorboard around the 2 - bolt flange on the header to get the best ground clearance. Once installed, connect the LS swap Y - pipe if you've purchased it. It'll bolt right onto the headers and your cat - back exhaust. As for maintenance, since these headers are made of 304 Stainless Steel, they're quite durable. But it's a good idea to check the gaskets regularly for signs of wear and replace them if needed. Remember, these products are for off - road use only, so don't use them on public roads.
