I got my JIC muffler installed and the work done was very dissapointing :x ... now seriously thinking about redoing the whole exhaust fitment with either a 2-1/2" or a 2 1/4" mandrel bent pipe for my dc2... just wondering which is better and where can i get it done ... i heard that liverpool exhaust is good but i dont have the address. does anybody have the address??? :?:
hey Royce,
here:
http://www.liverpoolexhaust.com.au/
when i called Livo i spoke to a dude named Shev, try asking for him, he's really polite and sounds helpful.
i believe most here will suggest 2.25" piping for your VTiR...
btw, the JIC muffler sounds meaty.. lol
jon
hey man, just get a full jdm cat back and u won't go wrong. forget about local custom made stuff and spend a little more to get everything right at the first time.
where can u get a full jdm cat. back?
royce! its eric! we talked about this mang! and u saw the proof on a certain vtir mang!
get 2.5 bro... and livo is fine mang! get a hiflow CAT with ur 2.5... and its all good...
leaves it open for getting headers later too!
but DEFINITELY, 2.25 is totally fine!.....
put it this way, if u prolly want headers later go 2.5, u cant go wrong....
otherwise 2.25 is fine too, cant go wrong! lol
2.5" i reckon!! i saw a certain beast (he's not on this forums) b18c1 (not in dc2)
2.25, go any bigger on NA and you might actually start losing power, what i was told anywayz, i got 2.25 with DRFT muffler.
Definately 2 1/4 mate.. I had a cat back HKS Hiper for DC2.. It was a bolt on kit.. Sounded mad..
I have 2 and 1/4 which is fine.
You can go 2.5 (ask slim)....
you may lose a little on the lower end, but gain a bit on higher end of rpm range.
more power go 2.5
my fren has dyno charts to prove it
he had 2.25 then changed to 2.5 n he got more power
on the dyno
2.250
checkout my thread in the civic section.
[Civic Type R goes on the dyno]
Then decide :)
2.5 inch is good for the teg
im warnin u now, it'll b quite loud
but u get used to it
Was that with extractors as well?Quote:

If you're interested at all... the DC2 Type-R has 2.25" exhaust from the factory, and I heard that some parts actually might go into 2" although the majority of it is 2.25"
hm..like son said i beleive 2.5" is the best for the teg.,.
to quote the integra info bible.. teamintegra
i'd recommend 2.25" straight through..Quote:
Most Integra owners have 1.8L engines with "bolt-ons only". You may want to look for a 2 1/4 in. diameter exhaust to start off with. If you begin to think about big lift-long duration cams, bigger 2.5 in. collector headers, headwork, or boring out to get 2 L displacement, then go up to the next levels in diameter as determined by your power goal.
2-1/4" up to 210HP @ the flywheel (about 180-185 whp)
2-3/8" (60mm) up to 235HP @ the flywheel (about 200-207 whp)
2-1/2" up to 265HP @ the flywheel (about 225-235 whp)
yeh phorte is right
if u wanna get heaps more power gains later
get 2.5
if u just gonna do bolt on mods 2.25 is enough 2
2.5 has extra 2 kw ova 2.25 from my frens dyno reading
depends on if ur gonna mod car more later down the track
gotta love team integra...
there's roughly 1/4 of a bees dick in it between the two- when talking cat backs and stock cat and header anyway.
thats right..
and i dunno what other ppl are saying about all these friggin power gains.. the power gain you'd get from a friggin header/exhaust upgrade on a n/a card is veryveryvery minimal..
the difference between 2.25" and 2.5" is extremely small. i couldn't feel it in terms of seat of the pants. however, the difference between 2.25" or 2.5" and stock is very noticable.
i'll have to take my car back to hill motorsport in pennant hills to give you a dyno chart, but others in the states are pulling ~10-15 whp depending on the exhaust system.
hehe its loud with 2.25 as well
haha
heyas thanks guys .... for the replies ... i've decided to go for the 2.5 mandrel bent cat back for my teg ... the whole package is a little to expensive :!: :!: :!: i'll start saving for the header for next years list of mods to do :D so we'll see what happens.
Yeah eric i remember ...
I got a quote for my the piping ... $1000 for 4 to 1 header, higflow cat, and mandrel bent pipe to my existing muffler.
or $350 for just the mandrel bent cat back to my existing muffler
hmmmm not sure which to go for ... quoted from fussy's of hume highway ... i think the catback sound more affordable. still waiting to get a quote from livo exhaust.
FUSSY...mate you should ask tofu-r for the next best link in town...
I got my exhuast done at liverpool exhuast, its a 2.1/4" cat back. It is quiet loud, i think if you get anything bigger the car will be very slugish, but you might get better power top end. I dunno, if you can tell the difference or not. But its loud.i dont think extractors will make much difference in the integ. But if you do get the whole set up i.e. extractors 4-1, high flow cat and 21/4" exhuast fitted let us know if there are any significant power gains. But if i was you i would skip liverpool and save up the bucks for the better stuff like fujitsubo ss around a grand i think.
kkekekeke...... waiting for boogets and ginggangoolys response to boosts reply..... dum di dum di dum :P
freid: Why have these guys got this setup? or what?
imo, brand name cat backs are a waste of money (in terms of the price difference)... performance gains over a good custom system are nill.
headers are a different kettle of tuna though.
i feel i've had some very good gains out of my system, but i'd have to get my arse over to hills motorsport to get some figures to back up my inner-ear dyno.
i've got some charts comparing a 2.25" and 2.5" cat back (on my car) though... and a stock dc2r that was at the dyno with me.
fujistsubo ss <<< what the ??? not sure what that is man could you elaborate dude???
so 21/4" is better im assuming???
Fujistsubo - Is that even how you spell it?
Anyways it's an exhaust brand!
if its noise ur worried about dun get zorst dude!
put in resonators to make it quieter, it doesnt restrict airflow
but hondas special vtec's r fkn loud!
2.5 is better in future if ur gonna go serious, like cams n stuff
wanna race?
hehe ill show u wat headers n 2.5 can do
kekeke
Hahaha...go race kraftykuts son!! hahaha
"Fujitsubo" is how you spell the brand....
I think that getting a wider exhaust cat-back will just make the car louder in the end, unless you really work your engine. All these power figures and gains that people talk about.... And fair enough dynos might be fun and show you how much power you have, but performance doesn't depend only on dyno. So a V8 can have three times the power on dyno than a Type-R but that doesn't mean the V8 will beat a Type-R on track, or in a straight line for the matter. Just saying whp isn't everything :)
And like I said before, 2.25" is the stock DC2R exhaust diameter. Might want to think about that...
and jap spec dc2r are 60mm (2.36) in diameter. also something to think about ;)
there u go... just get a jdm dc2r exhaust and ur good...
Stuff it all and leave it STOCKA BLOCK! hahahahah.
Its not the car but the driver... let me rephrase that... its both.
hehehehe... yeah i'll prolly go j-spec for my teg ... not really gonna do anything big anyways ... just make the car nice and neat and i'll be happy... but you know what i need now is some silicon hosing for my car red ones does anyone know where i can get them from ???
i've decided to go for the 60mm so i'm in between the two ... and i'm prolly getting it done at livo or fussy's. not sure yet.
booget: which headers have u got?
jdm 4-1
running 2.5 custom piping
dude, im saying performance wise as in power output from a 2.25 or a 2.5
2.5 will give u more power
but of course in terms of track n stuff its going to be diff!!
in terms of striaght line 2.5 will give u more power
bees dick thou, not much to notice
slim u nong post up ur dyno reading
btw that was me booget, on me frens comp
I'm planning to keep my headers stock standard - therefore no major mods to engine in future.
So I gather from all post above, a 2.25" mandrel bent is my best bet, right guys?
PS. What's the orginal size of the exhuast on the integra vtir's? Is it mandrel bent? Thanks guys :)
2.25"
http://board.performanceforums.com/g...-dyno1-med.jpg
2.5"
http://board.performanceforums.com/g...-dyno2-med.jpg
and one for the type-r buffs.
http://board.performanceforums.com/g...-dyno1-med.jpg
hehehe damn watelse u dun to ur car ginganggooly?
u got more power then a dc2r?
come on wat else do u have under there?
or isit just 2.5 full exhaust?
rofl
looks like 2.5 it is

wat version am i running?
most likely 2.23. be careful not to end up with the beta version either. it can lead to hydro-lock.
lmfao @ u shit-stirrers.... dont confuse us newbs.... biatches..... :P
hehhe sorry me bad, its christmas and im bored like a mofo
now im confused, i thought i had the 2.5 alpha version withh mutlipoint variable valve timing engagement?
no no no, the alpha version was only in non vtec cars. the alpha version conflicts with the muffler bearings in vtec equipped cars.Quote:

heheh
Looks like the question has been answered.
