My new exhaust install (pics included!) - Honda Prelude Forum

Dog_of_War · 03-19-2010, 10:55 PM

Okay so I know there are plenty of threads already about the Tri-Y header installs, but so what

now i have em too!

So i decided to keep my existing Greddy muffler - honestly to save a buck or two, and its in decent shape.

What I put in was:

Hytech replica header(s)
Official HyTech replica H22 Tri-Y header Group Buy!! - Preludepower.com
Magnaflow 54956 Center/Center spun cat 2.5"
Magnaflow 54956 Center/Center Cat 2.5" In/Out
OBX hgh flow resonator "Cherry Bomb" 2.5" x16"
OBX HIGH FLOW RESONATOR CHERRY BOMB MUFFLER 2.5"x16" : eBay Motors (item 390150533976 end time Mar-31-10 23:00:43 PDT)
and 2.5" pipe throughout

Had to get rid of the old SH header and heat shield

and

Thank god all the bolts came right off and no broken/stripped studs

Okay now I know how horrible my valve cover looks, and trust me I didn't hear the end of it at the shop putting all this in, so im looking for a new one(whos selling?!)

Fit just fine

And unfortunately we had to 'persuade' some metal that didnt want to get with the program

Once we got it in, the down pipe/s doesn't sit too low at all -

Welded up the extender(included with the headers) to the flex pipe and then to the Spun Cat

Some more measuring and then the resonator found its new home

Had to cut off the old pipe from the muffler and put the 2.5" on it

Then took it all off to put all the proper welds in place

Mounted it all up once it was cool to touch and presto!

The sound at idle is almost non-existent, a few times i kept checking my Tachometer to make sure the car was running

I don't know if the sound is deep enough for me, however it doesn't sound like a fart can that's for sure!, I didn't engage the VTEC on the way home, i don't live that far away from the shop and as it took much longer to install and measure all that 2.5" piping than I expected and had an

wifey waiting on me. I'm planning on letting the Lude warm up tomorrow morning and then taking it out for a spin on the turnpike. If I have the time tomorrow I'll take me camera and record the sound in the straight stretches of road adjacent our runway at the base.

I know the pictures aren't great quality but all I had was my droid so

I have almost the same setup. Different Carsound cat and different muffler. Same header, flex pipe, and resonator.

nope, not at all.. just welded a non fouler set up in the 2.5" after the cat

Is the resonator a glasspack, or does it use all stainless?

Paint your own valve cover, it is not hard at all lots of threads on it, did mine in wrinkle red to look like the red top valve covers and it came out awsome, a year later and still no flaking or cracks in the paint.

Nope all stainless, never used one before, but I'm definitely liking the sound output

skyyskyy · 03-22-2010, 05:59 PM

Finished up my Ghetto Type R valve cover...

Yea just picked up a new VC for pretty cheap, been looking on more than a few sites for tips on doing this, figure with an extra VC i have all the time in the world to get it right. Then i'll just swap VCs and sell the old one. In the process of more than a few 'tasks' on my Lude (I should be doing my own thread im sure), but first and foremost im trying to clean up my engine a bit and take care of odds and ends under the hood. VC first on the list

Seigisama · 03-24-2010, 08:27 AM

Good to see you got your exhaust on. When am i gonna help you get your springs on?

What would be the expected difference between the two? Performance, or sound?

after you swap, paint the old one before you sell it! might as well, sell it as a Type-S VC haha

Let me know bud!, so dam busy with work lately, but if we can work out a time then im all for it,.. got my lip kit to put on, just holding out till we drop her

Seigisama · 03-25-2010, 02:56 AM

I'm pretty much free on saturdays. I just gotta warn the girl ahead of time so she doesn't plan stuff for me to do. I work 2nd Shift so doing it on a workday is pretty much impossible. Except for the Friday before easter. They gave us off for that day. W00ts.

Oh and make some youtube videos so we can here her!

-Sandi · 03-31-2010, 12:41 AM

Looks good ! did you get a CEL light come on with the new exhaust.. ? Im also looking to replace my " fart can " that came with the car..

Dog_of_War · 03-31-2010, 12:55 AM

Thanks!

And nope no CEL codes for the sensors at all, used a spark plug non-fouler for the secondary o2 sensor, actually Ive always done this with my cars when i get them - hate getting codes for o2 sensors.

Seigisama · 03-31-2010, 10:35 PM

Can't wait to hear how it sounds compared to my OBX Cat back

I bet my 8 lb flywheel still gives me a performance edge

nimrod8560 · 04-05-2010, 07:48 PM

bump

Seigisama · 04-05-2010, 10:47 PM

Why did you bump it??

nordic97mist · 04-06-2010, 10:11 AM

exhaust looks good man. for the engine i would use purple power. that stuff takes grime/dirt off like an eraser
