>i am aware of the cracking over time, my friends header on his prelude cracked, and he was pissed.
but yeah, im rite now in a toss up between getting a header or dropping my car......soooooo idk what to do
btw whats the difference between 4-2-1 headers and 4-1 headers?
4-2-1 headers start off with 4 pipes (one per cylinder) that go into two larger pipes that meet and go into one larger pipe that leads to the rest of the exhaust piping. 4-1 headers start with 4 pipes that all merge into one pipe and lead to the rest of the exhaust. I couldn't tell you the benefits of either, just that that's why they are called what they are.
