okay... so i don't want my car to attract too much attention, noise wise...
this is what i was thinking about doing to somewhat maximize airflow while minimize noise..

sw intake
wr race header
wr intake mani
js racing b pipe
stock exhaust

what are your thoughts on this? and will it pass emissions????

 

A little heads up, the J's racing B-pipe has no resonator.
Id also suggest going with the Ep3 Si OEM muffler. Looks better while still keeping this lower toned.

Pretty sure you will have that after buzz as the RPMs fall down.

With a RH you will not pass emissions due to the car being deleted.

 

intake, header, intake manifold.. that thing is going to be loud from the FRONT.

 

And if you can't find an EP3 exhaust, the Megan Racing axle-back is just as good.
-- Racing header won't pass emissions testing because it has not catalytic converter.
-- If you want to minimize noise, then don't get a B-pipe that doesn't have a resonator or do get the B-pipe and just add another resonator.
-- Having the intake manifold will make the car pretty loud up from. Also, you might lose some warranty depending on how nitty-gritty your dealership is.

If you want quiet, it'd probably be better to just get an axle back (EP3 or Megan or stock), moderate B-pipe, and intake. Anything else is probably going to add more power and more noise than you'll want.

 

where you located?

 

mx, since it doesn't have a resonator, are you saying it's going to be a raspy sound? or a loud sound? what do you suggest i do then to partially free exhaust flow without compromising loudness?

cojaro, what do you mean by lose 'some' warranty? can you explain? also, the noise upfront is okay. i understand it will be loud, but it won't reverberate and attract unnecessary attention like an apexi gt exaust would.

kevin, i don't know the significance of your question, but i'm located in illinois.

and a general question, obviously since the cat is deleted with the rh... if i were to get emissions tested... would i be able to just throw in the cat? or do i have to completely remove the header and put the old one back on with the cat?

 

Kevin was asking your location because some states are more extensive with there emissions testing. If you were in cali (like him) you would be screwed but depending how your home state is will determine if your gonna pass or not. Most states, from what i remember, that actually test your emissions require some sort of cat but dont quote me on that cause all my tags are from wisconsin so i dont have to go threw the emissions crap and havent checked lately.

 

The dealer may say that the intake manifold caused something to malfunction, which would not be covered under warranty if it's an aftermarket manifold.

Personally, I would get the manifold, mostly because it would increase noise and you won't get the full benefit without a little tuning.

 

what kind of tuning software could i use?
i'm probably sticking with stock fuel pump / injectors / ecu (possible?? and would just be tuning afr's to accomodate the increased airflow.

for sure i'm getting everything but the exhaust.

 

No resonator and no cat is a combo of buzz and loudness. Even when paired to an OEM muffler. Itll have an after-buzz sound. It wont be noticeable inside the car.
And for tuning, I think a SAFC should be fine. Everyone else will suggest Emanage.

 

safc or vafc? don't forget it has vtak :P

umm i don't really trust afc's anymore. they're moreso considered an ecu hack, and seeing that i'm coming from hondata tuning software, i'd like something a little better than an afc, granted the price may be steeper.

any suggestions? i don't really know what's available for the fit. do they offer some kind of L-pro, like the K-pro? -_-
that was pretty lame ftl.

 

The Neo is what people use. I wouldnt mess with out VTEC, its worthless actually. Its on probably 95% of the time while driving.

I dont think theres anything out there for the Fit. Hondata says its tuned good from the factory, yet a Neo gained like 10whp on an auto Fit?

 

yeah i would rock the neo. but i heard the greddy ultimate works aswell.

 

mx, did you say vtec is on all the time? and what do you mean you won't mess without vtec? also, can you link me to dyno sheets and/or thread on a fit gaining 10whp just from installing a neo? i don't believe it. how is that possible when afr's / crossover point etc isn't even adjusted?

mr fit... why would you rock the neo? tuning capabilities or looks? and why do people use the greddy ultimate?

i'm sorry if i'm coming off like an a ss. i'm just curious as to what people are using and why they're using it.

we're all friends here

 

Theres a DIY on installing a VTEC light on the Fit. Its on anytime youre past 1/4 throttle. No matter what RPM.
So lowering/adjusting the VTEC's engagement RPMS are pointless. So basically you wont gain anything from it. So adjusting it would be a waste.

Havent you notice you dont hear or feel VTEC at all in the Fit?

I dont have a link for the dyno. Its in one of the Siphon magazine issues if I remember.
And the car had mods also. Intake, header, and exhaust.

 

so are you saying the vtec lobes on the cam are somehow linked to the throttle percentage instead of rpm?????????????

and no i dont have my fit yet. i've never even driven one. but i bought one and it's coming in sometime next week. lol.

since you're not adjusting vtec through the afc, are you only limited to adjusting afr's with the neo? or are ignition and other stuff also adjustable?

 

Throw a tanabe medallion on there. they're quite, but may ruin you're sleeper look. You'll get a couple horses too. (like.. barely.. haha)

 

will this work with a wr rh ?
or do i have to get a bpipe?

 

I'm sure it will. It bolts on to any after market mid-pipe.

(unless i'm missing something here)

 

okay.. so here's what's planned.
sw intake
wr intake manifold
wr race header
tanabe touring medallion

now originally, my question was do i have to get a b pipe to make the touring medallion fit? or should i just bolt straight on due to the race header's cat delete?
