sharing my exhaust setup.. Custom 2.5", KRRH, Race headers, High Flow cat, k24 swap

[imthebro]

Hi guys,
I looked on several forums / sites etc.. to see if I could find something that would resemble my final exhaust setup and never found anything...
I did not like the available "in the box" setups available in 2.5" or 3" as I found them to be either too loud or they sounded crappy. With the exception of the Apexi Ws2 that sounds good, but is too restrictive for a k24 swap.
And for the record; I hate chrome with a passion !

So I'm sharing my experience to help others in the same position I was in.

Car is:

• 2004 Civic SiR (canadian car Eh! )
• K24A2 swap

Exhaust setup:

• KRRH race header (no front swaybar due to that...)
• Vibrant High flow Cat - metal spun core 2.5" (200 CEL)
• Custom mandrel bent 2.5" Alluminized steel piping
• Vibrant ultra quiet 2.5" resonator
• Vibrant Streetpower straight through & flat black exhaust
• Injen Shorty intake

Sound clip (sorry, I'm not revving it to keep the neighbors happy)
Keep in mind the garage acts a bit like an amplifier in this vid.

The exhaust is not loud at al (but not stock either)l, it does not drone either.
and most importantly, it is not raspy at all (Aka, no shitty catless honda sound).

If anybody is curious: approximate total cost including headers, piping, installation, resonnator, cat, muffler etc = 1300$ CAD...

I'm a happy man now !

Edit :

Rev + drive away + fly by video (with traction issues and crappy shifting on my part)

I have received a few requests for pictures of my resonator & cat setup, so here they are (sorry for the poor lighting...).

weak attempt at a global mid-pipe picture :-(

very nice. i like the tone.

[02TWSI]

was that a cold start? Sounds so quiet shit, please get some on the road videos and some revving videos PLEASE.

Sounds GOOOOOOD for us cali folk.

[imthebro]

It wasn't on a cold start, but approximately 1 hr after I got home if I remember correctly.

I'll see what I can do about more videos...

My setup is almost the same and i'm on ephatch!

Slip_angle,
out of curiosity, are you running a front sway and if so, which one ?
I can't clear my headers with the stock sway... looking for an 05 Em2 sway as we speak.

I'm running a Hotchkis front sway. It doesn't clear. My first priority was handling for Autocross so I made the choice to modify the header slightly to make it fit.

Nice setup. I've got the same header/cat on my k24.

I just got my EM2 front sway in the mail, gonna install it this weekend. Someone else recently posted that this skinny front sway fit with their k24/KRRH combo. There are two EM2 front sways, you want the 15.9mm one, P/N 51300-S5D-A02.

I think I can get this new front sway to fit, the rear one is another story...

Nice setup! There are not many alternatives regarding the sway/header clearance issue. The 03' EX civic sway works well, and as should the ITR sway(with ITR lCA's).

Thanks for confirming the part # on this one man ! please let me know if it fits after you installed it. Are you using different swaybar bushings for this or the stock ep3 ones ?

My Progress rear sway fits my exhaust really well, but then again, the exhaust was constructed after the sway was installed in the back...

but without a front sway and with the progress rear sway in place, the car almost pivots too much... I'm still getting use to it. Fun in autocross, not so much in fast transitionning sweepers on the track...

[bchaney]

You need the 15.9mm bushings for the 15.9mm bar.

I'm having fitment issues in the rear because 3" catbacks don't like being stuffed under cars designed for 1.75".

Do you mean the car rolls too much w/o a front sway?

[imthebro]

nah, the rear end is so stiff with my progress sway, springs, etc.. that it rotates like a mofo !
It does roll a bit more, but its mostly the rear sway bar effect that is amplified.

Thanks for the bushing info, I'll make sure to order them as well

[T_Virus]

how many race headers do you have? KKRH, Race headers, ...lol

But you have a very nice set up.

[imthebro]

lol, I know, to be honest I wrote it that way because when I was looking for headers (not knowing all the accronyms used and not knowing much about headers period...)
It took me sometime to figure out what, BCRH, MRRH, KRRH meant...

[mitchlikesbikes]

damn that sounds good. if i ever go with a legit power making setup this is the way i'll be going. thanks for posting up!
