Ok guys, I have had the 545i a little while now and I am starting to get used to the small quirks and the big rewards. There is one thing that is missing for me at the moment, and that is the sound of the V8. With standard exhausts it's very quiet (which is no bad thing), but sometimes you would like to know you have a 4.4 v8 up front.

So I have listened to a few you-tube vids but they don't give you a real sense of the sound, or what they are like to live with day by day. So here are my requirements, let me know if you think anything comes close?

- I would like to hear the car at idle and on acceleration but want to cruise without any drone (very important)
- I am not interested in bhp gains
- Ideally the exhaust tips will look the same as OEM equipment
- I don't want to spend a fortune

Let me know what you think?

Regards,

JD

Yeah I'm know what you mean - although, if you give it the beans it *does* make a great noise, just you're very well insulated from it in the car. Try flooring it up to the redline with the windows down

I like you thinking, that's probably even more antisocial though

I suppose what I am after is the classic V8 'woofle'

Are you the same BMWBen from Pistonheads BTW?

I have the RPi exhaust and it sounds SWEET. The sound is sick, and the idle is just the right level. There is no drone when cruising but if you give it a little gas while cruising, you get some drone. You will get used to it after 1 or 2 weeks though. . I know you don't care about HP gains but the RPi gives you 13hp to the wheels.

Just bang a small nail into the muffler and pull the nail out.

Here's a link to my custom set-up, but this may be more aggressive than what you're looking for, http://forums.e60.net/index.php?showtopic=64616. The initial video page has a link to the interior sound clip for reference.

Check out RPI as well.

+1 for RPI

Not sure what you are looking for exists. No matter what anyone tells you the RPI exhaust in the 545 drones like crazy at certain RPMs.

I think you definitely get used to it though. I did it just took a little time.
I think the drone subsides a little after you put a few hundred miles on the car
And it doesn't drone when you are cruising. Only when you give it a little gas when your cruising in 6th gear. As soon as your off the gas it's quiet again

The Remus exhaust adds a nice low tone to the exhaust. Its only slightly louder than stock. See Remus Exhaust Shop for clips. You may want more loudness. No droning at all. The tips on the single side are a bit different than stock. I think my was mounted a bit rearward. They do stick out more. You can also get Remus quads and choose your tips but you need a different rear diffuser.
