That's friggin' sweet - I love that champagne color!

[jjs316]

hood actually looks like carbon fiber with a pearl clear coat sprayed over it.

Ill agree, nice looking ride.

[Reason]

I like the color too, I only seen one around here some older lady drives.

[sharky nrk]

NICE

[jjs316]

Did the wagon bumper fit with no mods? Looks like exactly what i need so i dont have to worry about cutting for JDM fog lights...

Its not the front cover and side skirts you have to worry about wagon to sedan it's the rear bumper that won't fit.

[Alcyone]

Yeah, everything fit fine. All you have to co is use the JDM bumper, b\c the USDM 5 mph bumper is too large.
Oh yeah, I forgot, you have to get the right grill too. I tried to put my stock '99 grill in. bad idea! It took 2 big gouges out of the bumper that i just had painted. :cry:

[Alcyone]

The new grill, painted and ready to go.

My Twin Loop Muffler install.
http://memimage.cardomain.net/member_images/5/web/2573000-2573999/2573964_27_full.jpg
I welded a adapter onto my stock pipe which I purchased at Advance Auto. It fit into the muffler perfectly, with a little persuading, but no clamp needed.

Sound clips?

[Alcyone]

Having no muffler on my car was loud as hell & sounded like a rally car! Not very good for everyday driving.
http://i220.photobucket.com/albums/dd282/alcyoneX/th_06e1ea5d.jpg (http://s220.photobucket.com/albums/dd282/alcyoneX/?action=view&current=06e1ea5d.pbr)

This is after my twin loop install! The car Kinda sounds like it has no muffler, but alot more quiet.
Now, this is a bad representation of what it originally sounded like before I tried a rolling 360 and spun out into an enbankment, smashing my brand new muffler. So it has a leak at the adaptor that I haven't fixed yet, but you'll get the idea!
http://i220.photobucket.com/albums/dd282/alcyoneX/th_b2717581.jpg (http://s220.photobucket.com/albums/dd282/alcyoneX/?action=view&current=b2717581.pbr)

If the clips don't work, refresh them. I had to remix it with Photobuckets crap b\c it smushed the videos, and sometimes it doesn't work.

NO MUFFLER! video clip (http://s220.photobucket.com/albums/dd282/alcyoneX/?action=view&current=MVI_0041.flv)

That sounded crazy. :twisted:

[Alcyone]

Yeah, I drove it for a couple days before I had the time to weld up the pipe and hanger on the muffler.
It was way to loud, however, I liked the sound. The camera really doesn't do it justice. It was so loud that it distorted the sound clip.
The twin loop, which I bought on eBay for $50, was the perfect choice for me b\c after hearing sound clips of how good it makes hondas sound, I new I would love it on my car.
I'll repost the sound clip when I get the leak fixed.

[SilentRacer]

Isn't that twin loop like really restrictive? do you sitll have your cats and resonators?

[Alcyone]

Are you kinding?
The whole point of getting one was that its not restrictive.
it's basically a dual straight through muffler that double muffles it.
Plus, I have a 2.2L motor and they need back pressure to make any power. I know this b\c when I drove the car without a muffler at all, it was a dog. The twin loop increased hp without sacrificing much torque.
I would really be screwed if I took out the cats.
My goal is the get the borla header, to help evactuate the exhaust immediately from the engine, keep the stock sized exhaust and cats to retain some backpressure, and use the twin loop to increase the rev range on the car and sound better.

Backpressure is NEVER good, and does not create power. Having an ideal exhaust diameter is minimizing backpressure as much as possible. You can create it by going way too big, or too small, but it does not create power. As far as a twin loop being restrictive, it is a straight through, but I just don't care for the idea of having such sharp bends in the exhaust system, I think it might be doing more harm than good. And if you get a Borla, and then keep stock cats, you'll be creating a bottleneck. The Borlas won't get exhaust out of the engine any quicker if the rest of the system cannot move the air as quickly - it'll only make the air move slower and allow it more time to cool off, increasing backpressure, and killing power. Air is a fluid (not a liquid, a fluid), and it cannot move through one part of the system faster than another part unless there is a leak.

[Alcyone]

You'll have to define "backpressure" for me then, b\c I don't understand how you can "CREATE" backpressure from an exhaust pipe that is too large or for that matter, no exhaust at all?
I can tell you for certain that my car loss large amounts of power when there was no muffler, and gained it back and then some with this new muffler.
The way i look at it, is like blowing through a straw. If the straw is very small, it nearly impossible to create alot of air volume at a set pressure. But if the straw is too big it does the same thing on the opposite sides of the scale, you don't create pressure and you exhaust air volume almost immediately.
But the the perfect size can create alot of pressure and volume for a good amount of time.
I look at that kinda like power & torque.

The reason I went with that muffler over other ones, is that i think that a few tight mandrel bends are better than a multi chamber muffler like 90% of whats out there. And straight threw mufflers sound like; well, why even have one at all?
ANd the borla header is a smooth bend, unlike the stock manifold. I mean, thats the whole reason mandrel bending is so popular. And as far as fluids are concerned, the smoother the bends, if you have to have them, the faster the travel reguardless of the diameter. That's why pipes are not square. Diameter is more for volume than speed.
I always thought the point was to get the exhaust away for the engine as fast as possible while retaining as much vacuum as possible, and a no backpressure exhaust only applies to forced induction b\c it doesn't rely on vacuum due to boost.
But quite honestly, reguardless of what the outcome of this debate is, i'm going to do what makes the most sense to me based on the mechanical knowledge i have and the hard facts of what i've seen and experienced.
Plus, it worked just fine.

[Huffer]

Backpressure is such a misleading term. I personally feel it's more about flow rate.
Props to you for giving something different a shot. It's well reflected in the car.

[blackgtbeauty]

Killah B333zzz!

Not deep enough for me. Definatly good for a 2.2 though.

[Alcyone]

Thanks Huffer for the compliment.
To all else:
just just wait, and be patient!
The header is coming soon, and the leak should be fixed this week.
that will definitely take some of the buzz away.
I'm sorry you didn't get to hear it before I wrecked it.
It sounded much better.

[what huh]

MAN i bought the twin loop three weeks ago hoping to be the first to get a video up but you bet me to it . . . sweet GT by the way

I'm not saying the muffler won't work fine.

And I'm not saying there's anything wrong with the Borlas. They're well made and perform ok for a disadvantaged exhaust design (unequal length just isn't great for performance).

Anyways, backpressure would be any sort of resistance to smooth exhaust flow. It could be created by several things:

Piping that is too small for the airflow - it crams the air in, but the whole system has to slow down because of the limited space for the air

Or it could be too large of piping - if the air has lots of room to expand, it will cool down and slow down within the exhaust system, which is bad for exhaust flow. People generally think that backpressure is only associated with small piping, which is why they associate backpressure with increased torque.

Put it this way - if you have super small piping, it'll probably work for low rpms and low throttle, because less air is going into the system, and you'll have "good torque" or good power down low. But once you get into high rpm, high load situations, it'll be choked and won't have much power.

It's the opposite way with too large of piping - at low rpms, the air volume is less, and the air will fly into the exhaust system, expand, and slow down, creating backpressure and reducing torque. But at high rpms, the air volume is much more, and the larger piping will be able to accomodate it, creating lots of top end power.

If you go with larger diamter piping in one part of the system, then go with smaller piping, and then go back to larger, I really think you're getting the worst of both worlds. If you have a choke point anywhere in the system, then your air volume will be restricted, which means the rest of the air in the large piping is going to be slowing down, thus reducing low end power as well as high end power from the choke point.

I can't wait for variable valve exhausts...

[Wiscon_Mark]

wastegate?

[Huffer]

^^ nah - more like the variable valve turbo that the Acura RDX uses.
Smaller diameter for low-down less spool up time power, bigger diameter for higher rpm WOT romp on it time.

Infiniti have true variable valve intake and exhaust cams now, with infinite positioning.
08 Accords will now have 3-4-5-6 cylinders for better mpg and power...

It'd be pretty cool if you could get an exhaust system (pipe, cat, axleback) to dynamically expand each chamber depending on throttle position.

[Reason]

I think Apexi makes something like this.

[deadlydave]

new Corvettes have exhausts that adjust based on the throttle applied. For low-rpm, these plates behind the muffler only open part way, for high rpm, they open all the way. Of course, they have a large-displacement v8, so it really doesn't matter in the low end.

[grayguy]

holy crap your car is hot! I would love to have that front end for my FMIC setup...

[Alcyone]

I would kill to have that FMIC & engine for my front end.

[Drakien]

It appears that the exhaust clips dont work anymore :( Could you post them back up? I was actually planning on getting that exact Ebay muffler! I would like to know what it sounds like with the 2.2 :D

[Huffer]

For shame...

[harrymaneuvers]

Reminds me of those celebrity comparison photos from then and now like for Lindsay Lohan

Where then was a beautiful, eye catching specimen and now just hurts to look at.

[Muse]

Sad to see it so rough. I'm diggin the roof rack tho...

[Thomistopheles]

Well, the car USED to look good... seeing that bumper so beat up made me die a little inside.

[EJ22D]

Everyone has hard times.
That being said, going from page 1 to 2 was a nasty shock...

[Muse]

Someone here should save it... Wish I had the money.

[r3v_v3ng3]

First time I've seen a BK roof rack bolted on a BD
