Well now I would hesitate on doing that if I were you until a few confirmations can be made. I spoke to a performance guy at Caffeine & Octane today that said that keeping them open slows the turbo spool up. Ugh! My guy is a guru too so I am not sure who to believe. I will find out more and post info.

Seriously? You lost low end torque with just the rear cans? I really want to understand this and hear from the mass of others who have installed E Race exhausts (or any others for that matter).
Dyno runs don't illustrate anything, right? As they're not really measuring low end torque. |

Here's a writeup for Supersprint's muffler. Interesting that they make the exact opposite claim:
"The factory one-piece muffler system has a complex design, which includes a built in flapper valve on one side of the system that has the sole purpose to alter the sound note at certain pre-set rpm levels. This design reduces performance at low RPM. Supersprint rear mufflers alone increase the torque and max hp by a significant amount, especially at low rpm." Will be worth testing this out! |

There have been reports of folks running Eisenman exhaust (early in the lifecycle) where the vacuum lines have been wrong or not attached at all, causing the car to run much worse than before.

I run an Eisenmann Race- zero tq loss--- dyno'd my car at EAS after the exhaust was installed. I dont think I gained any power but I didnt lose any either based on these numbers. The car runs very strong based on my tangible experience with 500+ hp cars. I did not get the exhaust with valve controls so my installer did plug the lines because if you dont you will not have any boost and essentially will run a 300 hp car. I dont care about the valves as I always want my car in the loudest format. FYI although the dyno graph says I have a center pipe- I do not... just axle back. The below numbers are SAE corrected too... std correction yielded 550hp.

The Beast is looking good thanks again!
The low end tq rumor was started a by a Cali company in the E60 M5 market since the eisenmann was selling better.

Exactly Nate. No muffler, straight through no restriction on a turbo car = faster spool up = more torque not less.

Deleting my ridiculous rant....completely beside myself to find out how the tech failed to properly plug my vacuum lines. Ugh...I should have investigated more carefully. Thanks to Ilya at IND for getting down to the actual apparent issue. Exhaust will be reinstalled tomorrow am with fully and properly sealed vacuum lines.

BTW-I had never heard that rumor although I know EXACTLY who you mean. I am basing this on my own experience period. Noticeable right away and was instantly corrected with re-installation of OEM system. Feels like a different car. In fact, I was following a 335i from the dealer in a spirited chase. He would stomp on it when turning onto different streets and I actually felt like I had to wait for the car to get up into full torque then I would close the gap. Trust me, I would have loved for the issues with the Eisenmann to have not been real. I want a nice deep throaty sound. I am not exactly an OEM guy with performance, looks or sound. We will be doing LOTs of business together-lol! Last edited by ColdList; 02-05-2013 at 07:45 PM.. |

It is ok to voice opinions but to tell me outright that I did NOT experience what I ACTUALLY experienced (as opposed to "theorized") is sort of like calling me a liar. I know that was likely not your intent but I still cannot understand how anyone could tell me "there is no torque loss" when they were not there and I actually experienced this. I am not giving opinion in this case. I am giving you absolute fact. Car ran like crap. Exhaust removed and OEM replaced=car fixed-definitive end of story (and yes those lines were capped too.) Kind of like me looking at the blue sky and you telling me it's green. Last edited by ColdList; 02-04-2013 at 06:53 PM.. |

Secondary cats are in the downpipes also. You have a 600 cell primary and a 400 cell secondary.

My dyno shows gain in torque. Did you dyno it?? BTW, ever heard of adaptation? You take it off and not let the ECU adapt or start right up, of course it will run like crap.
You are not a liar.. just inexperienced not my car so I don't really care. You can go believe what you want to believe Quote:
