The muffler is nearly finished. Enough that you can see the final product.

The center oultet muffler and a 934 W/G pipe would look pretty nice on your car.

Brian,
You have a nice looking system there. I had a few questions though:
What type of muffler are you using for this kit?
How is it going to be held to the muffler bracket on the engine?
Is there an O2 bung welded in between the muffler and the mounting flange?
Finally, this is all 321 stainless correct?

Thanks,
Fred

The entire assembly weighs less than 10 pounds so no bracket is needed. I am working on a simple way to use the stock bracket for those who have deleted the turbo bracket or just feel better having one.
The original prototype dual outlet muffler has been on my car for almost a year now with no bracket. It weighs 12 pounds.

Erik, did you ever get a zork? I'd like to hear one personally before I consider buying one.

I borrowed one and it's LOUD!... I haven't given up on it yet though as Ed Bighi and I talked in length about the factthat a k27 will change the tone due to the turbo impellers.. the stocker just sounds like .. well a 930 wit hno muffler... it's OK.. but for driving everyday it may start to bother you and or the coppers around here.. I haven't given up though.. I STILL want one.... I thikn Ed Bighi has the right idea.. i am going to see if i can work with him on getting one if not i'll have to fab one up myself to my sepc's....

Oh yeah .. I'll buy your wheels.....it'll free up some cash for you...

Nomatter the turbo, the zork is loud. That is why the above muffler came to be.
I tell all the interested folks if Harley's don't bother you then a zork won't either.

^^^^^ Exactly^^^^^^

I love my zork but I know I am going to get pinched for exceeding sound restrictions with the local clubs I run with at the track. Brian was good enough to work with me to develop the above solution. Because I had been running the 934 wastegate dump pipe with my zork and had a custom cut rear valence to accomodate the setup I really didn't want to have to swap all that out just to run at the track. This should really be the perfect solution for my situation.

I'd be surprised if this muffler is much quieter than a zork -

I had a cherry style muffler which is very similar in principle to Brian's muff, and now a Zork -
The cherry I had juuust takes the edge off - but not much at all.

I'd guess my point is don't expect much difference.
Not starting a pissing match, trying to help.

The nice thing here is technically you DO have a muffler, one less technical reason for a ticket -

Comparing the muffler body I use to a cherry bomb? I don't think I need your "help". Ha!
HUGE difference between my mufflers and the zork when it comes to sound level. I run this exact same muffler body in all the various configurations. Even the 965 style unit that exits the passenger's side is fairly quiet.
I'd say if you use a zork as a basline that my muffler cuts the noise level in half or more.

Brian,

So would you say that overall attitude or sound of this muffler is equal to the zork but at half the noise level? If it is just a tad bit softer than the original "neighbor hater" but retains the attitude, might be interested.

Anything will help your car. We could hear you loud and clear when you left Aloha Tower. The sound of you accelerating onto Nimitz was pure harmony.

Yup, wont deny that it is loud and you are right, the sound is so intoxicating. Shortly after the Aloha Tower, I picked up Brian's wastegate dumppipe and boy at full boost, it sounds like an F-15 on afterburners.

Although I love my zork, what I was thinking is if Brian's muffler is just like the zork with all the attitude, turbo-spooling, and raw sound but with a little, not much, lower noise level, it might be a good compromise.

I wanted a Zork, but didn't want to attract cops, esp on Kal Hwy late at night.

930LDR,

Do you have an azz shot of your car showing the Zork, WG pipe, modded Valence?

It's Friday, just looking for some car porn!

There are 2 options for the muffler.

The muffler pictured above has sound deadening material added and is about 1/2 as loud as a zork at the most.

The muffler is also offered with no sound deadening material. That version creates an expansion chamber that helps draw out the exhaust gases. It is raw and wild sounding, exactly like a zork but at about 1/3 less noise volume. This is the configuation I run on my personal car with dual outlets. It is about as loud as I deem acceptable for firing up at 6am. My brother describes it as "big block sound".
Cruising at highway speeds it is very quiet, on boost it is an animal!

I wonder if you can still shoot flames with this setup...
