well first off, whats soo good about the 4-2-1 or 4-1 headers? whats the diff between the 2 piece and 1 piece? and which one is better? ceramic or polished?

 

What motor are you running in your hatch? If its a stock D I would just not get a header or go with whichever of the two is the cheapest.

The difference between the two is top end power and low end power.

Again, whichever is cheaper of the two on ceramic or polished.

 

if its a d-series, and your stock one is cracked, and you don't live in cali...

EDIT: you live in cali..... if your header is fine, don't do anything.. there are better things you can do.. like suspension! or save up for a swap...

ebay stainless steel header 4-2-1 about 100 bucks shipped... or less...

--------------------

4-2-1 headers are normally linked with more midrange torque while the 4-1 headers are normally linked with more upper-range hp.

tho there could be some exceptions...

Exactly what I was thinking in terms of difference.

Even if its cracked I would rather pay $30 for a used OEM exhaust manifold then look into spending $300 on a DC Carb legal header. Remember... in Cali it HAS to be Carb legal.
