Is RPI planning to design dp's as well? I would love to be able to hear the turbos spooling.

We would also like to know who would do such shady things, but here are the facts we know...
1. GTHAUS is the only company currently offering a Successful and stable "ECU" tune for the F10 M5 and F12/13 M6 vehicles in US. 2. Recently we at GTHAUS made a +30HP gain with our Meisterschaft full cat-back exhaust alone on our F12 M6 vehicle. So, Naturally we have to assume (by process of elimination) that Nate @ IND, you are referring your previous VAGUE yet very misleading comment to us. If this is not the case, please inform us. We would like to know. The tested dyno numbers that we have published thus far (on our GTHAUS blog and on this very forum) are comparing our in-house F12 M6 vehicle with stock exhaust and stock ECU (NO TUNE) vs. the very same F12 M6 vehicle with only our Meisterschaft full cat-back GTC exhaust and stock ECU (NO TUNE). The dyno test was ran at a local, independent dyno shop and the result was a rather impressive one: Along with 30+ Peak HP gain, a generous torque gain throughout the entire RPM range (solid power band increase), however it is also true that there was a loss of 3 lbs/ft peak torque for a split second which is insignificant in our opinion. Simply put the posted dyno shows a solid power gains of HP and TQ - during our testing session at our local, independent dyno shop. Here is a link to our F12 M6 results: http://www.6post.com/forums/showthre...ghlight=gthaus HOWEVER... it should be noted that even though our 30+ power gain result is impressive, it is almost laughable for someone to assume that our TYR Technologies tuned, with Meisterschaft full cat-back exhaust only gains (+30HP) over a stock run. We can assure you that the results were far beyond that… LOL! Even with all these resources, technical capabilities, and advanced products at our disposal, we would like to express the fact that we are not yet bragging about our power / torque gains because we want to stay humble with our product offerings. It has been our style for years to let our customers do the raving for us instead of the other way around. We are very fortunate at GTHAUS to have a deep vehicle inventory to test on and thus have purposefully left our F12 M6 vehicle with a stock ECU and Meisterschaft full Cat-back exhaust system for comparison testing with our F10 M5 with TYR TECH ECU tune, which is also outfitted with our Meisterschaft full exhaust system. Below you will find a photo that was taken today of the F10 M5 and F12 M6 referenced above and also our current project cars parked at our warehouse. We invite anybody who is interested in our exhaust products or ECU tunes to stop by and check out these vehicles in person and to chat about the sound and power that we have gained from our Meisterschaft exhaust systems and also, the TYR TECH ECU tunes which is not just for the new M5 and M6 but also various different BMW model vehicles. The coffee is on us! Quote:

EAS is in to test the Rpi system. After that we will run the Akra, eisenmann and meister on AMS's dyno using a random customers M5 with no custom tune. This is a great time to post independent dyno runs since the beast just came out and this info will help the community out.

I'm pretty sure I have the most powerful M5 in the US! My custom exhaust puts out an additional 80 hp!
JK I haven't decided what exhaust to put on yet so my buddy made some 90 mm black ceramic coated tips. They put out 0 gains. For now, it's all show no go. |

How crazy would that be if there was an exhaust system that created 80 bolt-on horsepower?
Both your M5 and the tips look great .. Quote:

http://az79640.vo.msecnd.net/akrapov...2056fd4ec2.pdf From the dyno sheet it looks like it only has minimal lag on the low end compared to the OEM exhaust but catches up and surpasses near the mid-to-top RPM end. and the product website for the F10 M5: http://www.akrapovic.com/en/Automoti...ProductFilter= I wonder if the conservative performance and sound might have been influenced by the EC-Type Compliance that Akrapovic got certified for? Anyone from European countries know a thing or two about this? I'm assuming it's relating to noise and/or emissions? Not every customer is looking for a drastic increase in exhaust noise or only peak power. Quote:
I think it'd be great to post up the results of the dyno exhaust test shootout. |

Here is a link to an old (and basic) but still fairly useful article on the importance of how to read a dyno. I think the most important aspect that it mentioned was not to only focus on peak output. A knowledgeable owner is a happy one!

When I was deciding on which exhaust set-up to run on my F10 M5 I had narrowed it down to the EISENMANN and MEISTERSCHAFT ...
I wanted a high quality exhaust which produced a great sound and provided HP gain ... My E60 M5 was armed w/ a KREISSIEG exhaust which allowed me to go from quiet to loud with a hit of a switch .. I wanted this for my F10 M5 too!! I contacted IND and they were very helpful and told me that the valve on the EISENMANN didn't make much difference in sound ... So I went all in on the MEISTERSCHAFT exhaust ... It's a high quality exhaust system that sounds great, gives some HP gain, and most important for me allows me to go quiet when needed!! IM EXCITED TO SEE WHAT KIND OF HP MY MEISTERSCHAFT MAKES!! ps. Impressive stable you guys have up there and the ADV1 21's look much better ... Quote:

We have seen some very impressive power results with our Exhaust +TYR TECH ECU Tunes and would like to share this dyno graph and video with you guys. These are "power to the wheels" numbers. We will be releasing our Stage 2 Tune info soon as well!
LINE 1(RED) - F10 M5: MEISTERSCHAFT'S GTC (OPEN MODE) / SUPER GT + TYR TECH (STAGE 1) TUNE LINE 2(BLUE) - F12 M6: MEISTERSCHAFT'S GTC (OPEN MODE) / SUPER GT (NO ECU TUNE) LINE 3(GREEN) - F12 M6: STOCK - OEM EXHAUST (NO ECU TUNE) BMW F12 M6 stock (green) vs. BMW F12 M6 with cat-back Meisterschaft GTC open mode (blue) vs. BMW F10 M5 with turbo-back Meisterschaft GTC open mode and TYR TECH Stage 1 tune. We just posted up much more info regarding our TYR TECH ECU Tunes in another thread. If you're interested in learning more about TYR TECH ECU upgrades, there is more discussion on it in the link below.

I'M DOWN FOR THE REDLINE!!!
All the talk about POWER POWER POWER has me itching to begin the next phase of my F10 M5 projekt which is increasing the HP!!! But RPiM5's statement/challenge makes me curious what kind of HP my M5 is now making with the MEISTERSCHAFT GTC system + LXR pipe w/o any ECU tune .... M5POST thoughts? Quote:

Torque curve looks good and the HP seems to plateau nicely for a bit from around 3,300 RPM but is there a reason why there seems to be such a dramatic drop off in HP from around 4,600RPM and onward? Is the engine running into any issues or is this how the TYR tune was set for? |

I started the same thread on the M5BOARD and this recent reply caught my attention ...
Check the dyno graphs: Is this right? Quote:
