How do i get an exhaust for Ek4?

[**Ghost**]

Hey guys, as some of you know i own an EK4, and nowi'm saving up for an exhaust... basicaly i know wot Cats are, wot extractors are, wot mufflers are, and what piping is... thing is... i haveno idea what "CatBack" means or nething like that...

basically if i was looking to get an exhaust... thats 2 & 1/4"" (want performance and a LITTLE noise, not defect style) could i get the parts separately? cos i really hate the stock exhaust i have right now, makes no nice noise to speak of...

Like can i get a muffler first, then a high flow cat, then extractors? (and of course piping in between)...

Or does my civic come with a stock 2" exhaust and i have to get the whole set otherwise i end up with stuff thats all for 2" an di would never be able to go 2 1/4?

thanks guys...

First off "catback" means the piping/exhaust from the cat back hence the name, if u know wat the cat and all the other stuff is u should be able to work out that u will just be getting the piping from the cat back and most prob the muffler as well. The order i would go is get the catback system first then the extractors and then the high-flow cat if there is any use. And i would think ur civic would have a smaller exhaust then a 2" and yes it would be a waste getting the muffler and all the other stuff to fit ur stock exhaust when u are better off getting the catback and working on from there.

any particular reason why you want to go 2.25 inch and not 2 inch?

you will notice that mugen only make a rear muffler for the EK4.
Mugen believe that the stock piping is good for around 200hp before it becomes a restriction.

I believe 2 inch mandrel bent piping is a good system, any higher and you'll end up losing response and low end torque

I paid $160 for my 2 1/4 catback... got a fair bit of low end out of it... lost a little up around 6000Rpm but yeah low end is awseme. I use it more than top end so it was a great move

Before my car used to lag up until 3000 now it kicks around 2400-2500 mark.

It will pull from 1500RPM to 3000 fairly quickly... in 5th gear. I very rarly change out of 5th ever since i had it installed.

Thats why i'd go 2 1/4. If you want more top end back get 4-2-1 extractors.

sikcvc: what exhaust did you have before??
usually when going larger u lose low end and gain top end but your is all backwards :s

I had the stock 1.5 or 1.75 what ever it is...

The exact same has happened to my mates VR, he went from 2 to 2.5 and he has HEAPS of low end and same top end. worked well for him.

are you sure about this? this is the first time I've heard of losing power at the top end by going up to a larger diameter.
also do you know if its a mandrel bent system or a press bent system? for the price I think it might be press bent.

a general rule is, get the optimal mandrel bent system, or go a quarter inch more but in press bent.
I think the mandrel bends would be better tho as it gives a smoother gas flow.

Yeh kit i heard about the mugen thing... they're big advocates of "keep it stock" piping in this area...

well i thought 2 1/4 inch would be good compromise between noise and bigger top end... any bigger and i heard that i'll start losing too much bottom end...

but yeh... 2 1/4 or 2... was going to speak to a professional about...

how much am i looking at? (for catback, + muffler) .... presuming i want some quality brand but not Spoon or nething like that... extractors i;ll get brand name... normal piping i mite just get a Lukey or Genie or something

any recommendations???

its mandrel bent... and yeah i'm sure... my low down power has definatly increased. my high end has deminished slightly... That or its mearly expanded the points at which it gets major power... eg kicks in lower.

I'd say thats what could have happend since it does pull earlier than stock and maybe because of this it doesn't feel like it pulls as much as it did up high.

I cant explain it any other way but that.

as for the costs, Dads mate doesn't pissfart around when it comes to exhausts he knows his shit and gets stuff for the price its worth thats why i got it so cheap. Think about it... theres only one way for the pipe to go (down the channel in the chassy) its $10-20 worth of steel and with a jig mandrel bending isn't hard nor expencive... once of bends cost a fortune... Hence low price...

I want to know how you guys can justify paying such high prices.(ie $900 etc) even for headers I'm getting Tune length mandrel bent Polished 4-2-1 headers for $500ish fitted for my new engine.

anywhoo... I'm ringing the guy tomorow I'll ask him see what he says... he's been doing it for 25odd years so he knows what he's talking about.
