    Best headers for a slammed car?

    Hey guys,

    I've been researching and can't seem to get one answer, people say ITR headers will give good ground clearance and some say it will hang too low. Also is it true that fitting a b18c headers to a b16a will give better ground clearance? My headers atm are pretty much fuxx0rd and will most likely need replacing. Just want to make sure that the headers I'm replacing it with will give me a better clearance.

    Also have thought of putting skid plates on the new headers that's going in.

    Cheers lads.

    Re: Best headers for a slammed car?

    B16b and B18 blocks are taller so they will hang lower to the ground on b16a.
    IMO to get the best fit possible buy some 4-2-1 and chop/weld the 2-1 piece so its the right height to provide the most clearance or if its got a real thick flange you could mill it down a bit.
    4-1 headers will be a real pain to do tho but it can still be done.

    ITR headers are average as for ground clearence.

    Toda have awesome clearence, otherwise i havent seen many that have good clearence

    Stock headers I would imagine have the best clearance.

    b18c headers are a b16a do not have better clearance.

    4-2-1 have a better clearance than 4-1.

    Your average 2-piece 4-2-1 should have decent clearance. My Tanabe tuck up into the sump nicely. I'd be more concerned about your sump. I just wouldn't bother with 4-1 or Tri-Y 4-2-1 (like Hytec's).

    Re: Best headers for a slammed car?

    won't this depend on chassis & motor combination?? Get a bash plated welded on in a shape like this \_______ but with a less steep angle. Don't bother with password jdm clamp on ones they suck.

    Re: Best headers for a slammed car?

    4-2-1 over 4-1. If you want 4-1's, go something like ITR 98 spec which are staggered configuration which tuck slightly higher. Steer clear of any boxed config's like TRR. If your running a b16 go with b16 specific headers. B18 headers will sit a further 20mill lower. A good set of headers should be higher than the sump.

    Re: Best headers for a slammed car?

    Just run OEM headers if slammed is your priority. If you're that slammed its not like performance is that important because chances are it'll handle like shit and you wont be able to drive it fast anyway.

    If you want a bit more power on the cheap go ITR with a 2.5 inch flange or if you want a good performing header which is parrellel to the sump then buy my Spoon 4-2-1.

    Re: Best headers for a slammed car?

    I would just get a skidplate welded onto your new headers, i had 4-2-1 FGK headers on my EF9 and they were tucked up really nice, but my sump then came in contact with the ground. I would rather have the bash plate on the headers hit the ground than the sump.

    FYI the difference in block deck heights between B18C and B16A is only 9.1mm, so not sure where people get the idea that a given B18C-specific header hangs waaaay low on a B16A.

    Werd!

    I've got some snug fitting Spoon and Feels headers that are designed for B18C and they're still super snug on B16A's. 9.1mm sounds about right. I'm just modifying the rear header bracket so It can brace the B18C header on my B16A block.

    Re: Best headers for a slammed car?

    There is a difference in sumps too which add to why b18c headers hang sooo low. The windage tray on the b18c requires the sump to be bigger.

    If you want spoon style 4-2-1 but with an improvement for better performance - John @ Canary Automotive has a set of primary pipes sitting in his workshop and he can easily make the secondary pipe to go with it.

    This. Last thing you want it your header to be too high and bottom out your sump.

    Run any header, then get a piece of 3mm alloy about 500mm wide that attached onto the rad support all the way to the subframe.

    Rally skid plate FTMFW.

    Do it

    Re: Best headers for a slammed car?

    I have just got a set of 5zegin headers for my b18cr powered EK4, they sit low but am welding a 3mm S/S bash plate to them. Will be more than enough to stop damage to them and save my sump.

    This seems to be the general consensus!

    Re: Best headers for a slammed car?

    But welding a bash plate onto the headers stops the headers from denting but not the studs ripping out of the head when you hit the big one? Or putting a nice crack through your head from all the knocks.

    Just food for thought....

    If common sense was prevailing nobody would have a lowered street car. ud have to be pretty unlucky to break studs header more likely to shear or fold. If you can stand to loose the extra 2hp for vtecing off from the lights factory headers are the go

    Have you had this happen? I've hosed a few sets of headers from being low, never had either issue. Also bust a sump... obviously its a possibility - but i dare say an extremely unlikely one. Weld on plate ftw.. don't bother with clamp on ones they are shit. And imo better to have the headers/bash plate sharing the load with the exhaust system and 10 exhaust studs than the sump

    edit - rally skid pan ftw, shame honda rad supports are weak wouldn't be attaching a low hanging steel plate to one
