Default aftermarket header vs stock header height

generally, will a stock or aftermarket header hang down lower in the car. this is for a custom application, and i need as much ground clearance as i can get. i have the stock header, i was just wondering if i go to an aftermarket header, will i lose or gain ground clearance?

my stock headers, when layed on the ground, and the flanges are made parallel with the ground, the height is about 6 inches.

thanks for any input,

When I put my headers in, they sat exaclty where the stock ones were before. the plastic undecar shell fit back in place with no problems.
I guess you should be asking more specifically with regards to the aftermarket header that you are currently looking at...

some headers will in fact give you less clearance. I cant remember specifically but out of the 5-6 header brands ive installed i distinctively noticing the loss of clearence with a number of them. as for gaining clearence, i doubt any header will be any shorter than the stock manifold

I've heard that some of the eBay headers hang quite a bit lower than OEM. The rest fit identical to stock from what I have researched.

Stay away from those SSAutochrome ones on eBay. I believe they're also called Stone Mountain Racing or something like that. They hang very low in the front.

The gp-moto 4-2-1 headers hang lower and actually hit the skidplate and will burn through it. You loose a few inches with them and with all the other 4-2-1 headers of the same design.

i have been useing the SSautochrome Headers for a while now. I was running the group-s headers, but the ssaurtchrome headers have given me increased hp and torque levils even over the group-s for a fraction of the price. Given the firment of the ssautochrome is more of a pain, and isn't constructed as well as the group-s but for $250 what do you expect. I just ground the internal welds smooth around the flanges, and all is well. They do hang lower than stock I will agree there, but all the other aftermarket headers that I have seen so far do that as well, aspecialy the 4-2-1 headers.
