Personally i'm getting 2 inches not only cos of money, its also cos i know i dont wanna turn my EK into some KW monster, at least not ne time soon. I'll be willing and able to fork out for the piping if i thought i needed it...

I'll ring x-force and ask... but can neone tell me, minus the cat and the muffler, is the EK4 stock exhaust piping really heavy? or not a noticable difference?

btw i took a look under my car at the mechanics ( to get a good look at the piping) it seemed rusted on the outside,,, is that a problem? or is that just normal?

you're funny. how the hell will getting .25" of extra piping make your torqueless monster a kw monster LOL! :D
In any case I would go 2.25"...CTR is 1.6 and comes with 2.25"

hmmmm... how in the world did u get the impression i was having a go at u? ust doing some research here before i fork out the 1000 or so i'm going to spend :?

maybe the reason why all the performance jap ones are 2.25 is cos they are designed for track use therefore not concerned with low end loss?

man so many internet mechanics nowadays. I wish i could do that fora living, i woudlnt have burns and cuts on my hands all the time :(

someone said b4 (think it was speedcore) somethin bout not usin local made parts but i think u should look into some of the australian companies cause there are a few aussie companies out there who are actually building the parts for companies such as 5zigen and so forth so i dont think we should go and rite off aussie made stuff straight away

I meant Speedcore's post :)

Offcourse you should do your research when you spend that amount of cash. :)

if u got 800 to spend, get a jap system
you won't need a hi flow cat until you get extractors if you ever get to that point

i went 2inches too
unless someone can prove that 2.25 makes any reasonable gain at all..
then wahts the use?
for 1.6l, 2' is known to be the optimum size, any bigger and u'll lose some bottom end as well as gaining nothing in topend.

My take on the benefit of having mandrel bends, all the bends are smooth. ;) Even where the bends are, the diameter is constant. Press bent, at the bends, the diameter can decrease, bottlenecking the exhaust flow. And the finish is just much better.

i've also heard that 60mm or 2.38" is optimum for modded B16A engines.
Heck, i got me self a 2.5" anyway as the exhaust place had been getting good results with that diameter....i got it dynoed before & after too. From 93.1kw [2" catback] to 98.9kw [header, hfc & 2.5" system] 5.8kw peak gain.

The results showed that the new system followed the old, till it got to about 3500rpm where it overtakes the old system. So no loss in low end. Guess the header helped out a bit in that department.

But each to their own !
and please...no replies about the high readings... :| http://www.ozhonda.com/forums/album_pic.php?pic_id=553
Tell ya what though, my vtec change over point has lowered itself from 5.5k-6k rpm, to 4.8k-5.2k rpm.

LOL man I'm lost.... I don't know what you guys are talking about. If its any help.. I didn't get offended by anybody.... we are having a discussion here. :?

Yes I would do research on everything and make your own decisions, especially with expensive stuff like exhausts.

LMFAO!! Wipe your chin cause you dribblin' verbal diahorea!

hey just wondering... a good intake (not sucking hot air) and a good catback... + a hondata tuning afterwards, owt changes would it maketo the car?

would it change the vtec switch point? change the speed (KM/Hour) i can rev to in each gear?

in terms of 0-100... take maybe a too hopeful 0,5 seconds off ET?|

more important is extractors than catback
biggest gains are gained there
