2.25" -

both on my car ;)
hope that helps you decide.
Thanks for that dude =)
Brings me one step forward atleast
Don't forget to look at the bottom half of that graph also.
true, take note of it. i lost a fair bit of low end with the 2.5" system. but it was worth it IMO. when you are pushing it the car lives int the rev band from about 5800-8000. so it's all good for drag racing, or tracking...Quote:

as a general rule of thumb you would lose either top-end or low end...in a perfect world you could gain both...if not maintain power output....
a larger ID (inner diameter) B-pipe is what you really want as VTEC likes to breath...
cheers
fanx heaps
ginganggooly wat other mods have u done to ur car? if u dunt mind sharin?
lots and lots of secret stuff :wink:Quote:

cams and cam gears on order... and i'm still deciding on what route to go down in the way of electronics. powerfc, unichip, chipped ecu, etc.
It would be interesting to see how you would go on the strip.... :lol:
any pics??
Slim,
Are you going to keep the car or keep doing it up?
i'll probably stop after i finnish the next lot of work... i'm more or less happy with the handling setup. and i think there will be enough power to keep me happy when the cams are installed and tuned.
if you don't plan to do too much to your car, a 2.25" system will give you good power throughout the rev range.
I would agree with you on that one...good point! :wink:Quote:

yep, check the dyno plots, there seems to be a jump in power around where the secondary runners open up. otherwise the 2.25" system was better.Quote:

What headers are you running? Is it still what liverpool mufflers put in?
4-1? or 4-2-1?
4-2-1. yep, gen-u-ine hurricane header :D
Have you thought of going 4-1 custom made? (as they don't manufacture 4-1)
i have a set of mugen replica's 4>1 that i made 120 odd kw atw with (with other mods) - let it go for 450 if ya want it... its for b series - i had it own my dc2R
if you can..
try and get a set of "dave flood" headers..by far the best..
can be seen on Aus' fastest N/A Fwd and on the Autosalon N/A dyno comp winner (DC2R)
4-1 are the best for 'B' series hondas
is this the 12.8 b20 vtec civic?
he's running a livo exhaust header too. dave flood modified it for the owner. at least thats what dave flood told me ;)
i asked him to make me a set about 2 months ago, but he was busy and never got back to me...
nobody runs JDM 98 spec OEM 4-1?
whos this dave flood? :roll:Quote:

i think dave flood's header would be the go if you were planning to do other mods to the car. the fact he can take into account things like changed redlines, cams, compression and all the other little things involved in doing a serious build up means that he could make something specific for your machine. think of it as comparing a pre-programmed chip to a programmable ecu.
back when i was shopping around for a header, the jdm 4-1 version was extremely hard to find and over 1k.
who actually makes the mugen replica?
as i said, i'm lettin my mugen replica go for sub $400... a $1000 hmm wher'd ya gew that figure...
dunno about who makes em but with a bit of elbow grease on the dremel, she's looking good and clean!!!
I was running a Dave Flood modded Livo header. But now I'm running a header that I made myself. It made 11 whp more than the old header. I'm sure Dave could make a header from scratch that would make the same improvement as mine......maybe more.....who knowsQuote:

What's the contact on this guy, & what's a ballpark figure?
Best bet is to PM him on Performance Forums. I know he checks it daily. Tell him Chuck sent you :wink:
don't say chuck sent you....just say you want to beat chuck ;)Quote:

jansenrw - what would it cost for postage to sydney??
I can probably do it through a friend of mine who owns a floor polishing business for about $10-15 but will have to double check. This will not be door to door but pick-up from a point...
I'll double check everything for you, remind me with a pm and I'll give you my details!!!
wheres the best place to get my exhaust done at??
im plannin to get a 2.5inch cat bak exhaust plus muffler

jus got a quote today
$550 from turbo exhaust (wetherill pk) mandrel bent 2.25" cat back with muffler
i asked liverpool exhaust alreadi. quoted me $600 for 2.5" mandrel bent cat back with muffler
=)
so whats your choice then mate?
It might take a bit longer for things to get done at liverpool exhaust because they have plenty of customers but I like the people there. I've been back a few times to weld bits and pieces and they haven't charged me because they remember I keep coming back :)
I have a Brand new Stainless Steel Cannon Muffler in a mirror finish. for sale $170.
It has a 2.25 inch inlet and a 4 inch tip.
Email me for pics if interested.
