Sorry guys. Haven't gotten a free moment yet to pull the DynoJet run files off the dyno computer. I'll take some time later today to grab the files and post up the dyno results for you guys. In the mean time here are some shots of our new high flow 100 series midpipes.

Are you using a 4 wheel drive dyno or disconnecting the front drive shaft?

Gorgeous!!! Remind us all the pricing, availability?
P.S. So when are the headers going into development? You have come this far....might as well close the loop!
Any insight to what is used for cats? Also, find a way to delete the cats and pass inspection
You will have my business. I'm not sure how far you want to dive into the 100 Series, but I would think a high flow aluminum intake pipe (to replace OEM intake resonator) with vacuum ports, that is properly tuned to eliminate AFR flutter, and a nice set of headers to go with that exhaust, would sell nicely. The 100 market needs new players with new ideas, otherwise we are stuck looking like each other, and sounding like each other. I see 80's on the trail and they all look different. I see 100's on the trail and it's copy-paste.

It's mainly standing at the rear that you can hear the difference. And keep in mind that these sound clips are without a silencer/resonator. If you want it super quiet, you have the option of getting the exhaust with our silencer/resonator installed. Wear some headphones or listen to these with some good speakers. It's VERY hard to judge the sound properly on a laptop or phone:

Even with the O2 sensor mounted flat to the pipe it shouldnt throw codes. But when going to a single cat or no cats at all it will keep the check engine light from coming on.Sweet!
Assuming the lengthened o2 mounting pipes keep the ECU from throwing codes?
2wd dyno. Center diff locked, Front driveshaft removed.
Pricing on first page of the thread. Cat-back is available right now, midpipes will be available to order tomorrow (friday). If there's enough interest for a good set of properly designed headers we can make them for sure. We should have time in December or January to do the R&D and prototyping if there's enough interest.
We're using high flow stainless steel shell cats. 48 state compliant (will pass sniffer/computer test in CA, but won't pass visual). We can build a setup without cats no problem. We will be doing an intake for the 100-series around December/January.Any insight to what is used for cats? Also, find a way to delete the cats and pass inspection

Very quiet, guess I'm getting old because that's what I want!
Just so people have an accurate benchmark. The LX470 in the videos/sound clips, does it have just the EMS cat-back, or also the EMS mid pipes and hiflow cats? Also does the EMS cat-back have the standard muffler or the optional add-on resonator as well?

The setup on the truck in the videos is our standard cat-back exhaust with no silencer. Stock mid-pipes. Stock headers. The high flow mid-pipes will change the tone of the exhaust slightly (a little deeper) but will not change the volume.

Perfecto, thank you!
Call me what you will but I can't find the Midpipe pricing in the first post.
Would the mid pipes direct replace stock? I'm currently running DT headers and have hacked a Magnaflow into the stock cat-back section... but my cats are pretty rusty. I would consider the mid pipes sooner and you cat back later if it can be made to work. Will the mid pipes fit in an otherwise stock set up?
Thanks a lot,

Thanks a lot,
Does the system retain quality sound throughout the rev range while driving? For instance my Flowmaster setup sounds great low RPM. After about 4,000RPM full throttle I lose the exhaust sound and it just turns into a high pressure air sound. Does the EMS deliver a V8 sound without the ugly whooshing sound? My biggest pet peeve is loosing sound quality when air is trying to escape. My 100 has it bad
Sounds really nice. I like a very mild deep sound in these types of trucks. I'd love to hear it with the mid pipes and cats.

Dyno charts
I finally had a chance to grab the run files off of our dyno computer. Here are the charts.
Details on how we did the dyno testing:
* All runs done with shifter lever in 2nd gear and "2nd start" button depressed. This assures that we are able to start in 2nd gear and stay in 2nd gear throughout the entire run for the most stable and repeatable results. (numbers would be slightly higher across the board in 3rd gear, but on these trucks there is no way to keep it in 3rd gear without shifting).
* All dyno runs done in 2wd (rear wheels). Front driveshaft removed, center diff locked.
* This was on an LX470 that was totally stock except for 33" BFG tires.
Graph details:
1) Baseline dyno, all stock
2) Dyno with EMSPowered catback exhaust, everything else stock
3) Dyno with EMSPowered catback exhaust and EMSPowered high flow midpipes w/ dual cats (one cat in each pipe)
The first graph is UNCORRECTED numbers. Here at EMSPowered we like uncorrected dyno charts because they do not have any sort of arbitrary calculations that change the true numbers. Uncorrected DynoJet graphs show true power that is being made to the tires with NO other calculations. The second graph is STD correction showing what the numbers are with STD correction factor calculations (calculations to correct numbers based on air temperature, humidity, altitude, etc...). As I mentioned, here at EMSPowered we like UNCORRECTED numbers, as they are the actual numbers being put down with no trickery or weird calculations.

No problem.
Midpipe pricing and ordering information will be posted tomorrow. Yes, the EMSPowered high flow midpipes are a direct replacement for the stock midpipes. You can use them with a completely factory exhaust, or any combination of parts. As long as the stock midpipes fit in your setup, so will the EMSPowered high flow midpipes (except they would flow more and make more power).
Yes! Definitely! The exhaust sounds great from idle all the way to redline. Personally I prefer the sound without the silencer, but for those that want a slightly quieter the silencer makes the exhaust very quiet. Without the silencer there is absolutely no "wooshing" sound as you describe it. With the silencer you can hear a slight "wooshing".
I agree! A mild deep sound is perfect for these trucks.

Wow! I'm no engine tuning expert, but those results certainly exceed my expectations!
Any thoughts on how the impact would be on the 06-07 VVTI engines?

I'd be happy to do the before/after dynoon the VVTi motor for free and installation free if someone with a VVTi 100-series around here wants to purchase one of these exhausts.Wow! I'm no engine tuning expert, but those results certainly exceed my expectations!

Am I reading this right?
Your test vehicle was dyno'd stock at 138.8HP (uncorrected) and 145.96HP. How on earth did a LC loose 81.2HP (uncorrected) and/or 74.5HP (corrected)? I also see a 24HP gain with your full exhaust, which is quite impressive without headers. If these trucks are loosing that much horsepower I may as well be prepared to start pushing it up hills around 2016. I am hoping I read it wrong, but numbers are numbers...
