best of luck and perhaps you will be better with stock. |
I've had non-factory exhausts before, but they didn't drone. I had a factory-equipped E90 between my E39 and F10 (which was even quieter than the F10) but still....
My PE, on my car, installed by me has one area of character I don't care for. There are lots of times that a low throttle angle and/or the way the turbo affects exhaust sound makes it that all there is is low tone. This is what makes the drone etc... Then you get on it a bit and get some "rasp", or "bark" or whatever you want to call it. If there's no rasp involved, I don't really care to drone around with low tone all the time.
Based on general Internet feedback, I'm going to triple check my installation.
Also,
my part# is 18-30-2-293-447, just in case there's more than one exhaust out there for N55 535 and we aren't even comparing apples-to-apples.
Crap - just googled. Our mufflers may have different part numbers:
http://bmwfans.info/parts-catalog/18302354362 shows 18-30-2-354-362 includes mufflers 18 30 2 354 365 and 18 30 2 354 366
http://bmwfans.info/parts-catalog/18302293447/ shows that 18-30-2-293-447 includes mufflers 18 30 2 293 448 and 18 30 2 293 449
I'd really love to know the difference from an authoritative source.
This thread (
