Finally got my car fixed and got a BMW Performance Exhaust installed but...

So after my car got rear-ended by a Tacoma...my car was taken to the BMW Collision Center to get repaired. The repair took nearly 7 1/2 weeks because the main impact of the collision was to the exhaust which shifted a bunch of suspension components, damaged the mid pipe, downpipe and shifted the turbos. After talking to the person in charge of my car he was able to get me a BMW Performance exhaust instead of the stock exhaust.

The Exhaust sounds amazing on cold start and on deceleration when it just burgles and pops. The note of the exhaust itself when acceleration gradually, sadly sounds like a riced out fart can (a lot of buzzing sound)...i did alot of research prior to getting this exhaust and have heard nothing but great things about the sound and tone. What could be the cause of this? Do you guys think maybe it takes awhile for it to break in? (Driving about 200 miles so far) Perhaps the clamps aren't tightened enough? Im pretty much stumped, because i would assume the install was done right since BMW did install it.

Never assume a job was done right because a dealer did I it lol
There should be no rattling or buzzing associated with the exhaust, does it sound like a loose component or clamp?

I would give it a few weeks to break in. Or get some vibrant resonators

Break in, mine sounded ricey at first as well... I have catless dp's, vibrant resonators in place of the secondary cats and it sounds awesome.

It kinda almost sounds like a civic with a huge ass 5zigen exhaust...lol...and at other times it sounds as if something inside the muffler (packing) is loose

Since im heading over to LTBMW to get some work done next week...i might just have them double check and make sure the clamps are on tight..and if they are give it some time and let it break in...hopefully after that itll sound as amazing as what everyone says

As far as vibrant resonators are concerned, are they going to lower the loudness of the exhaust?

I just got my Bmw performance exhaust today on my e92 335i and i am sooo happy with it! It does Sound a very small amount ricey but im young so i kind of like it. if it goes away thats fine. if not then thats fine too. I watched him do the install so i know its on correctly. I really couldnt be happier and i cant wait to put some catless downpipes on it too!

Do you have an AT? If so, AT's have the tendency to drone with the BMW PE as mine did. I sold mine to someone who had a MT and he didn't have any problems.

I am on my second performance exhaust between two different E90's and I have never looked back. I think it complements the car perfectly.

Only way to remove that tin can noise at 5k plus rpm is to put vibrant resonator in place of secondary cats.
