question, I'm going to replace my original stock downpipe elbow with a stock ported exhasut elbow. Which bolts is best to remove first. I guess I should use ultra copper (high-heat make a gasket stuff) when bolting on the new elbow. What size are these bolts just in case if they break/And how do u guys get to the bottom bolt on the turbo exhaust side(one bolt in the back-bottom). I can do it, just asking if there's a method to start first.out, looks tight?
