i did a search already
but didnt come up with anything that wanted to know
bascially, i wanna know whats the difference between this and the N1
from reading the werid english ont he spoon site
im guessing this gives a bit mroe torque low down
or something liek that
in the future, i was planning to get a full spoon exhaust system with the street type muffler
what you guys think?
The flow of Spoon street type = Stock Type-R + 5% increase of flow
i am not making it up, spoon use to have the comparing data on their site before
street type is more quiet and offer less exhaust flow. the flow is 124 litre/sec while N1 is 139 litre/sec. Standard is 112 litre/ sec.Quote:

Strret type is heavier at 5.2kg, N1 is only 3.6Kg versus standard of 8.5kg.
you want power... go for N1. if you want a bit of perfomance but also more quite.. go for street type.
If you want power and quite.. i have not seen one a straight thru system that is extremely quite.. maybe there is.. but have yet seen a genuine race purpose muffler that is quite.
well the N1 muffler comes with silencer... so thats good.. when u want to race.. put it off.. and on the street put it on.. easy bolt on with the silencer
:D
thanx hondar
just the info i needed!
one more thing
does the N1 cause any low end loss?
i have a feeling it does
what do you mean by low end loss? you will lose power if your exhaust piping is too big... or you use improper piping size for your car...Quote:

remember this rule as well... "there is no replacement for displacement", if you want to make power you need the cc. thats why people have been modifying and come out with b20 hybrid, or people go for h22 swap becos in bigger cc, you get more torque...and therefore they feel the power from the moment they rev the engine...
my personal preference is still b18 but to each his own i guess...
back to the topic.. spoon muffler is 60.5mm which is just nice to me and i dont think it is too big
thanx hondar
much appreciated
so the full spoon exhaust would be
4-2-1 headers
b pipe
and the n1 or street type muffler?
approx how much would that be?
spoon has 4-2-1 and 4-1.Quote:

however i have exhaust system coming in real soon... just watch out for the traders section. :thumbsup:
would it be save to assume that 4-2-1 are the ones where 4 pipes connect as 2 pipes then to 1 pipe and 4-1 is 4 pipes conenct as 1 pipe? and would it be... correct to assume there is better air flow in 4-2-1 ??? i'm not sure how can i search typing 4-2-1 lol or airflow in exhaust... well... exhaust gases in this case. positive replies much appeaciated!
the spoon n1 is a good exhaust as for the spoon headers,..they are really good but because of the thinner metal used, it is advisable to wrap them with extractor insulation
mate the design of 4-2-1 and 4-1 is got to do with the exhaust flow. it got to do with primary runners, secondary runners of the pipe. the length of them. it is designed to affect your peak torque landing at certain rpm range.Quote:

at the end of the day peak torque is where you want your engine at. so next time your look at dyno sheet, dont look at kw only. look at the torque curve as well.
actually it got nothin to do with thinner metal used. :D (im not flaming you okey..) it is good of course to get product from the same company as they wont do a bottleneck system.Quote:

but you made a good point about extractor insulation which can be useful to have them wrapped if you dont have a heat shield. a good thing to do but not a must thing. there are other things that can make you go faster.
coming back to spoon system, it is 60.5mm all the way so it is a good system in that sense to have them if you dont know the sizing but if you know,it doesnt matter if you use apexi header, vision b-pipe and hks muffler as long it is not bottleneck.
hmmm so whats the proes and cons of a 4-2-1 and a 4-1? i'm certain there is a reason why there are 2 such system of piping... o.O, sorry still learning X_X
thx for the advice!!

what gear box you have will have an impact as well, what final drive you have, will have an impact as well... what race you are in, will have an impact as well :D :D
hmmm okay never though extractors can be that complicated aswell ... gotta do mre research! thanks!! ^_^
thanks for the advice hondar!!
4-1 gives you higher top end, with losses on bottom end,..while 4-2-1 foregoes some of the top end gains for better overall across the range. If it is daily driving,..4-2-1 is better in my opinion.
the jdm ek9 and dc2r both have 4-1 right?
but that about the audm dc2r?
well, it depends how you drive as well... it is very subjective...some people the 4-1 generally gives more gain at higher end compared to 4-2-1 but it does mean necessarily that you will always lose bottom end. most of the time you see no gain or very little gain at bottom end in which you dont really need anyway becos most people are driving in mid and high end band most of the time unless you are stuck in M5 or M4 on monday morning going to work and there has been a huge accident in sydney's road.Quote:

bottom end is like 0-3000rpm roughly... are you going to spend most of your timer revving at that range?
or is it 3000rpm -6000rpm mid range roughly...
or 6000rpm and above?
and dont forget you need to match the header with your gear box and its characeteristic.. what its your 1st,2nd, 3rd,4th and 5th gear ratio. and yes that include auto cars.. becos auto cars do have gear ratio as well. what is your final drive ratio...
what you want to happen is that after each shift you want to land at rpm point where it is already at peak torque. thats where you gonna win the race.
hmm... but.. how does it come to play??? does lower gear ratio means better or worse...?? i'm seriously confuse and overwhelm with this O_o all the while i just just install it and you can enjoy the benefits already =/
it is not better or worse...it depends what kind of race you are into. and yes you can usually enjoy the benefits (or feel the gain) using the so called your dyno butt :D but you will be able to gain more if you tune them properly.Quote:

erm... i'm getting a 5Zigen exhaust, 2.5" i reckon
will it have a difference on my ride?
what is your previous setting? have u done any other mods?Quote:

if you just put a muffler alone and has not done anything else... i dont think you will feel any gain. there will proabably gain if you put on dyno, but not much you can feel if you use "butt dyno" which is important to many people since most of us dont go for real dyno.
anyway since we are on this topic, when you change such i,h,c,e (intake, header, cat and exhaust) technically speaking you are not making more power but instead you are liberating more power. it is more of unleashing the car potential power.
remember honda cars are mass produced and they one thing in mind is to pass rta emission control in australia in terms on noise and pollution.
i would recommend getting the whole cat back system at least. but again not many people think that it is necessary so... i leave it as it is..
well i know money is a factor and i have said many times that even i need to save up to buy parts for myself. so you need to start saving and buying parts when you are ready. thats why i prefer certain brand becos the parts can be bought separetely. like the b-pipe and the muffler can be bought separetly so offering people flexibility to buy parts one by one when they are ready... again my 2cents
yuppers, thanks
so no one'z used a 5zigen before.
no worries. lol
i'll have to dyno my car soon on my private butt dyno. lol
i've planned the steps already, just that i'm acquiring an exhaust and i wanna know how it sounds and all.
to be honest i love "butt dyno" myself LOL :D cheap and you really gain a huge satisfaction but unfortunately not the best way to do it.Quote:

yeah, my current muffler is loud and bassy, i like that and i don't mind it because i'm used to it but me mates are complaining. lol so...... 5Zigen was a good choice so i hope it's fine.
thanks mate
hmmm can any1 tell me the different between a catalytic back exhaust (did i get that right??) and a non catback exhaust? they look like the same... lets restrictive airflow? lighter? both?? sorry for all these questions but i did ran a search just that the peeps were talking more about 'get a catback' instead of the difference and such.. not really what i was searching for .. either that or i didin't go deep enough =/
