Car is getting louder and louder

MPULSV6 · 6th March 2006, 00:20

I'm at around 6800 miles now, but at 6400 or so, my wife and I took the BEAST out for a 230ish mile road trip. While driving back, I had a chance to really open her up but noticed that the car has gotten much louder since, say 2000 miles. I was beginning to wonder if I had a puncture or something in the exhaust. My wife swears I did something to the car (since I have modded just about every car I've owned, except this one). I also noticed that 4th gear seemed to have gotten stronger (I could be imagining).

Is this normal? If so, I guess I won't be needing that Eisenmann exhaust.

FUnny you should say that, I am now at 4200 miles and my brother who had not heard it since 2000k miles ago said the same thing to me, and he is a sports car guy (not a poseur), he said it is definitely louder. I also noticed it myself today when opening it up in p500 at low rpm it has a nice loud bark to it, just love it and makes me wonder if bmw knew that the exhaut would open up with time. No complaints here and in a way anything louder at this point would be too much for me as a daily driver

Yes the car gets louder after the 5000 K.m break in period.. I have been told by someone from the factory that there is a substabce in the exhaust that wear off after 5000 k.m thats what makes the car sound louder,, i really dont know if thats true or no...

I wish mine would get a little louder - it's too quiet! (9000km)

Exhaust systems do tend to change tone & volume with use. In general (THOUGH NOT ALWAYS), better exhausts get quieter (due to soot filling up the mufflers), lower quality exhausts get louder (the glass fiber packing sound packing in cheaper mufflers doesn't last as long as the steel fibers in more expensive mufflers, burning off).

So, which exaust have you installed?

Mark, you will have to get Hartge mufflers, drive it harder, or just drive the yellow one more.

yes. i've noticed the same. my car is at 3200 miles and even cruizing on the highway i can hear loud and clear the exhaust- this was not the case at say 1500 miles. also when accellerating i noticed that car is much louder.. very nice.

methinks the exhaust finally cooked and sealed and is transmitting the sound better.. happens on all cars..

nevertheless- a welcome change.

few cars

I'll try option 2 for starters
