[MPerformance]

Hi Everyone,

I finally did my breakin service on Tuesday after several LONGGGGGG weeks. These 1200 miles seem like an ethernity at first but I did it. While I painfully tried to get through this breakin period I was busy planning all my mods and shopping for parts. This actually made the wait time even longer. After weeks of researchs, youtube, and reading tons of reviews. I finally decided to go with the akrapovic titanium exhaust and the eisenmann downpipes simply because of the eisenman brand. As you know Akrapovic isn’t a cheap date by any means. I figured at least the downpipes would be easier on the wallet but heck no. These damn eisenmann downpipes were expensivo! Over 2k for just the lowers lol. I found tons of reviews on the akra exhaust but was unable to find any reviews on eisenman downpipes. But I wanted the best so I bought them anyway. A few weeks went by and I stumbled across raving reviews about Kellerperformance downpipes having the best fitment and the best quality on the market. Their pricing are not only cheaper, they are 3D scanned and much lighter than eisenman as well. I decided to contact Mike KellerPerformance and bought their new 3.5” coated downpipe. That was the best purchase I EVER made. These downpipes are not only stunningly beautiful they are soooooooo well made. Literally fits like a glove as my technician said. I couldn’t be happier and couldn’t returned these eisenmann quick enough the moment I was able to physically see the quality of these Kellerperformance downpipes. These Kellerperformance downpipes and the Akrapovic exhaust literally transformed the car into God of Thunder. I don’t get paid for writing this review. Simply wanting to share my experience with all you fellow enthusiasts. Definitely contact mike @kellerperformance and give these downpipes a try I GUARANTEE you won’t regret it. Mike is super accommodating and easy to work with. Props to Kellerperformance!!! Beating eisenman in quality says a lot about this company.

Here are two links of what my car sounds like after the installed:

How much are the Keller Performance pipes?

Did you try the Keller downpipes/remove resonator with the stock M Performance exhaust for the M5 Comp before going to the Akropvic or is that not possible? thanks.

Curious as to the total labor time to install upper and lower DP's? Hoping that someone can provide that answer just to know what to budget for this mod.

Anywhere from $400 to $800. Anyone that quotes $800 is charging too much.
