Spoon and mugen have come up with extractors for the Fit respectively. Won't be cheap though.Quote:

i went to a muffler shop the other day and they said that its useless to change it
there will not be a noticable increase in the performance..correct me again if im worng...?
Had a friend that got his changed to local custom stainless steel type. But its' a 4:2:1 instead of stock 4:1. Complete with dummy cat and straight thru muffler, I can't catch up with his in straight runs especially the high revs. :D
To have a better effect, best is to mod the header(front end), the cat(mid end) and the muffler(rear end) all in one go. I reckon a 4:2:1 extractor actually boost the low end so low end torque is not affected too badly in this config? I heard reckless tampering of exhaust equipment might end up losing excessive low end torque. Gotta practise so caution is this area. :o
The consensus with Hondas in general, is that it is pretty hard to beat the factory headers on most models.
Personally I believe it is a waste of money on the Jazz unless you are trying to get every single possible kw out of it. The Spoon and Mugen items will cost a bit over $1,000 each.
I have had a look at the standard headers on the Jazz and they look pretty damn good for a factory unit on a budget pricecar. The Spoon and Mugen items will be geared to high rpm performance (they are a 4-1 design).
I found that there was a bit of power to be found by replacing the exhuast (it was noticeably, though not huge), and I also have some doubts over the flow capabilities of the stock cat, but that opinion is based solely on the strange/akward design more than anything.
thats what i had in mind... i want to change it to 4 2 1 as well...i did the the cat and the muffler so the headers is the only thing i have to do now... how much did ur friend have to pay? i got charged $550 for the stainless headers.. i didnt do it cos the shop said its use less...
does ur friend have to change the catalytic converters? or just use the factory one?
4-2-1 will give better low to mid response. 4-1 is more top-end.
so do u reckon i should change it ? will it give a better performance?
I'm not (yet) because I don't think believe the cost justifes it....
But that's just me. If you want to get a few extra kw and aren't worried about the cost side, then yeah do it! I think most gains will be found in replacing the exhaust sytem and cat
$1000 for a header is okay man compare to yr custom intake for $400 altogether
I may able to give u an idea how much gain it will have after the header arrived
It wont be that soon since spoon dun have any stock and jdmyard still waiting for the reply
Yeah I know what you're saying TypeG....
Anything on a small NA is going to cost a fair bit and give minimal gains. I just don't want to test the waters on this one (I am yet to see or hear of any reports on the performance of the Mugen or Spoon headers). I did it with the intake and it seems to be coming along quite well, but the wife wouldn't be overly impressed if I started playing around with extractors at this point.
At the end of the day, I do want a set of those gorgeous Spoon headers, I just can't justify the cost at the moment. It would be more for 'JDM bling' more than anything because only a select few would have them and I like to be different.
dun worry
i will tell u if it is worth or not
lol
wait for me
hehe
TypeG where can u get a spoon header? locally? or order it from Japan? have any idea how much does it cost? does it make a difference when u custom make it? or just for the sake of the brand?
u can get spoon headers through tanghy or hondar, they have to get it from japan so there is a wait.
they cost about a $1000 maybe a little more (cant remeber).
bbc03 - do you mean custom make a copy of the spoon headers or a tuned length set of headers here?
Pete :)
$1000 for headers??? wow..... anyway, what i meant was getting a tuned length set of stainless headers...but then i could easily make a copy of the spoon as well cost half of it i guess but change it to 421
which one do u think is better?
actually is $1180
custom one depends where u go and may cost heaps
i ordered from jdmyard
hm... i prefer 4-2-1 but 4-1 will do for me since th length is not that long anyway
custom work vs spoon or mugen.... i have no idea but u pay for u pay for .... maybe right maybe wrong
lol
all depends on yr wallet i think
I think you also have to appreciate the amount of R&D that goes in to the Spoon and Mugen products BBC03. Sure a local exhaust shop can knock something up for you, but it will be a bit of a hit-and-miss affair. VTEC engines are known for being tempremental when you start modding them, so sometimes it is better to spend a bit extra and know that a lot of work has gone in to producing a quality and reliable product.
You might not get huge gains, but you won't be as likely to suffer power losses which seems to happen all too often on vtec equipped engines
