I'm willing to pay +$20 for an even quieter exhaust. As fate would have it, I bought the 12579 from 18psi NIB. He values silence as much as I do and he's seen and heard TONS more of these setups than I have. I trust his (somewhat questionable) judgement

I am guessing you are going for the ARTECH routing as you posted in post #4. I need to add some installed pics of my setup with the muffler at an angle. I have no interference issues or rubbing and it was easy and cheaper to install (one 90 less to buy). I did add all poly exhaust hangers though.

Have you heard one of these 22" mufflers before? It is super quiet. I actually wish mine was a little louder. It is super stealthy on the street and not that loud at WOT either. I know you guys out west have to be a little quieter at some tracks, but damn, if you add a resonator it will be a wisper!
Thanks! We'll see how well it fits the bumper cutout once it gets here. I'll post pics.

Time to face facts: I'm not going to have the EFR in the car for Miatas @ MRLS in September ![Tear](https://www.miataturbo.net/images/smilies/tear.gif)
Why?
**** what needs to get done:
If I have time, maybe:
Its not a terrible list, and without the actual 140~ish hp SuperMiata horsepower "cap" maybe we can squeeze a couple extra horses out of this BP4W. Should still be fun and totally attainable.
![Tear](https://www.miataturbo.net/images/smilies/tear.gif)
Why?
- Manifold and downpipe aren't here yet
- Exhaust system parts are not here yet
- Once the parts get here, it still needs to be fabricated
- Donor for built motor isn't even in the shop
- Intercooler mounting/plumbing isn't mapped out
- Oil/Water lines are not completed
- I've been working a minimum of 58hrs/wk for the past 3 weeks and I don't see this changing going forward
- I'm in Las Vegas this weekend so that's another whole weekend lost
- There is no way in hell I have time to complete this in 3 weekends
**** what needs to get done:
- Ordered RacingBeat "Race Connecting Pipe" to complete exhaust
- Order parts and build SuperMiata style intake
- Install monstrous TSE radiator
- Fix my stupid ducting
- Port Squaretop for 64mm throttle body
- Install Squaretop + Hondata gasket + 64mm throttle body
- Finally install Carbotech brake pads
- Brake ducts
- Install aftermarket gauges (specifically oil pressure, oil temp, coolant temp)
If I have time, maybe:
- FM framerail braces
- SuperMiata damper + 4T wheel
- Find out what Andrew @ Trackspeed wants for a couple of hours of N/A dyno tune time
Its not a terrible list, and without the actual 140~ish hp SuperMiata horsepower "cap" maybe we can squeeze a couple extra horses out of this BP4W. Should still be fun and totally attainable.

Well Damn! Sound like you have a good plan already. With that resonator you should meet your sound goal easily. I was seriously surprized and almost dissapointed when I started my car with the 12578 for the first time. Couldn't hear a thing. I now vaguely remember the center/center one being reported to be a little quiter when i did the research for my build.
Sorry to hear your track day plans are going to crap. If it makes you feel better, mine are too. I was planning one the first week in October. Would be the first one since the turbo went on the car. I set a goal to have the thing on the road for proper tuning and shakedown runs before end of July so I could get everything figuired out by the end of September. All that got screwed when I blew something in the MS2 this past weekend!
Oh well! Good luck!

I used a 12589 with one center and one offset because I was not sure how the inlet routing would be. Allowed me to use front, middle or back entrance from the mid-pipe. Ended up using the center and the offset was for the exit. So, you should have no problem with the center / center.
Sound is good with this muffler and the big 3" Cat (P/N 59959), which I would expect to have similar sound effect as the resonator. Not perfectly quiet, deep throaty with no droning, and no ricer fart sound.

One of the guys at work emailed me this afternoon and ask why there was a pile of boxes for me at the office that, and I quote "sounds like a robot orgy when shaken." I think my exhaust components have arrived

The nice thing about the NA track car setup is it's just a show up, check oil, drive car type-a thing. That'll be perfect for the relaxed miata's @ mrls track day atmosphere.

DNM: Thanks for the pics. And yeah, I bought tight radius bends because I figured that would be easier to fit. In fact, I did 16ga mild because the available radii were tighter from the vendor I chose to use. It might not be "ideal" or "optimal" but I'm sure it'll be fine for my goals.
EE: Yep, a well set up Miata at speed is a helluva bunch of fun at the track. It just sucks to miss the goalposts. And really, I'm not that impressive a human being, just a guy with too much time on his hands.

And its not even my car! ![Biggthumpup](https://www.miataturbo.net/images/smilies/biggthumpup.gif)
You people rapidly forget how much of a giant wuss I am.
Koto: did you have the NSX out on Hwy 68 sometime in the last couple weeks? I think I spotted you. Red NSX really stands out in a crowd

Yeah. During the summer months the windows on my house here just stay open. I drove the NSX around without windshield wipers on for two months because I took them off to paint them and just never bothered to put them on again. The funny thing is that the locals complain that it's "freezing" and break out the umbrellas for a light mist.
