JASMA aka Japan Automotive Muffler Association is a trade association not unlike SEMA. They work with member businesses to ensure their exhaust systems meet necessary standards for quality, noise and emissions regulations, etc.

Simply having a JASMA certification label on your exhaust manifold tells us very little about it. You will need to share detailed pictures if you want help identifying the manufacturer or specific model. You manifold might be rubbish or rare or both or neither. What's most important in an aftermarket header is condition, fit, weight, power, and legality. Many RHD headers don't fit LHD cars. If it's rusted to hell then it's rubbish. It probably isn't all that rare.

had a look about on it... HKS super header aparantly

any good? been used a little but no rust what so ever...

 

[freedomgli]

HKS is a well respected brand but I don't know anything in particular about that header. Are you located in England and are you driving a RHD car? If so you should have no trouble with fitment. Does anybody know if HKS made more than one header design for the 1.6L motor? I'm sure there has been a review of it in R&S or details about it in HyperRev. If not, check out http://www.hks-power.co.jp/

In Scotland mate

RHD as well

fitting was easy enough. had to remove one of the lifting eyes temporarily to get the old manifold out and the new one in. cheers for all the info so far. i'll keep investigating

How bad are those dings? Bad enough to affect performance?

It will definitely affect performance.. the reason why it's bashed in is because I was "attempting" to make the primaries clear my LHD steering shaft, I came up a couple mm short of clearance..

Hence, I am selling it for 100 + shipping so that the next person has extra cash to modify the primaries to work with our LHD cars. If someone is willing to do the work, they can have a pretty great custom header setup.

I do have a HKS Racing Header Type II on my LHD 1.6l NA and it went just straight on, without any problem. :wink:
