Just curious to know if this is common...? He put his header on today and noticed a crack all the way around one of the 4 pipes. I was just curious to know how this happen and if it happens often. The car is a 98 Civic EX with like 70k miles on it, so its not all that old. Thanks

Happened to me too, 93 Si, about a 2" crack along the Cyl. 2 pipe near the flange to connect to the bottom half of the header. caused a hissing sound, one of the many.

It's pretty common on 96 and 97 models. I've only seen a couple of 98s crack.
