You keep making it plural.lol what about them crash
There are four primaries, 1 flange, 1 collector equaling to 1 header to bolt onto the 1 headed 4 cylinder motorwell yeah lol, there is 4 pipes, so its plural haha
It does sound better when you say "headers", but you're going to get a TON of s**t for it. Like here.crash u just shut your mouth u smartass lol..... i dont know why i add another letter, thats just how i have always said it, and when im talking to someone it sounds better if you say, im going to add my headers, rather then saying im going to add my header lol
