Eisenmann Race exhaust on 2014 (lci) 550i w/ N63tu
Correct me if i'm wrong, but it looks like these mufflers will work on any year F10 550i. I installed a set on my 2014 550i with the N63tu motor which makes more power than the outgoing N63 motor, and the exhaust sound DIFFERENT on the LCI car. I know the downpipes are different on the LCI, they are more like those from the S63tu motor, so maybe that has something to do with it. The exhaust sounds AMAZING however there is a slight 'BURP' or 1 second 'exhaust gurgle' when I get off the power, when under full load. I can tell this is boost related as I have to have it floored, the boost and revs build up, and as soon as I let off, there is an exhaust burp. What am I listening to and is this common? Did not find any mention of this on prior years, or am I wrong?
Thanks in advance. |

Terrible/shaky video I found but you can hear the noise i'm describing when he gets off the power and hits the brakes. You will not hear it under full throttle when its shifting through the gears, only when you get off the power..

Also the newer LCIs (2014+) motor no longer uses blow off valves in its N63TU powerplant which is something it seems to have gotten from the M5's S63tu, however the older F10 550's did have diverter valves. Could this have something to do with it?

its back pressure from turbos that you are hearing all N63 TU cars sound like that and M5 i love it , thats why i upgraded my 550 exhaust with 3 inch piping and M5 mufflers.

YA I have the blurp when I left off the gas. Sounds pretty cool. Lol
So older f10s don't do that with exhaust? I thought it's just not having cats didn't think it would be related to year of the car. |
