I'm pulling the trigger in the morning. It's either going to be the Eisenmann Sport, Dinan Rear, or M Performance. I've talked to many of you on here and read over the many threads thousands of times and watched all of the videos. . They all are different and will give me more noise. Here are my conclusions:

1. M Performance - $3500 - No Drone - Less Bass - Higher Pitched Exotic Note - Perfect Fit since OEM. 20LBS lighter than stock. Titanium Perforated Tips, cans hang a little low. 2 yr BMW warranty. Highlights the engine at any rpm especially over 3000 rpm. Has a lot of character. Does not pair well with x pipe.

2. Eisenmann Sport - $3400 with connecting pipes - More Bass - Heavier than stock - Slight drone at 2,000 rpm's. Fantastic quality. Great 83MM tips. Deep sound under 3000 rpm then more engine note over 4000 rpm and exhaust goes silent. Pairs well with X Pipe.

3. Dinan Rear Section - $2600 - no drone - only two functional tips - decent bass nice improvement over stock. Pairs well with Dinan Mid Section or Turner Test Pipes. Tips don't look as good. Some reported fitment/quality issues.

I've had the Eisenmann on my E60 535I and enjoyed it. If seemed like it did not have enough of a range in tone. Just bass at low rpm! I know a twin turbo I-6 is a completely different animal than a V8 but I'm not sure if I want more bass that disappears at 4,000 rpm.

The Dinan seems interesting as everyone who has it enjoys it, and the lower price tag will allow me to do more mods, possibly pair it with the Carbon Fiber CAI although a drop air filter in will give me the same gains. Not sure how the black tips will look with the Jerez Black Sedan.

M Perf is near the top of my list as the only negative that I have heard is paint flaking on the inside of the exhaust tips which can be removed. It may suit my style better since DD/Kids/Wife.

I'll let you know what I do tomorrow. You guys rock, everyone has bent over backwards, and reached out to me to help me make my choice.
