In most cases, it is best to install it into the exhaust port and then align the pipe to it. Tighten the exhaust pipe flange nuts in alternating steps so that the pipe draws to the head evenly. |

| + | "I don't get it, I have swapped back and forth from SE to stock depending on pipes for years and never had an issue intalling the stock gaskets. Yes they are more difficult than the SE but you just work them in one edge slightly in then in a circle pattern until just the edge is in all the way around then keep pushing them in in the same manner until they are seated. Then I take and run my thumb all the way around the inside to make sure they are completely smooth. When installing the exhaust you do so CAREFULLY. Leave the clamp out of the way and pull the heat shields if you can't see up there perfectly. Center the pipe in the gasket and hold tight, slide up the clamp, install the nuts and tighten them evenly. Then again the SE ones work good too and are easier to install. I think if the stock head pipes are on it and you can get the stock seals installed and done correctly that they will last longer, but hey to each is his own." | ||
