Straight piping 750li too loud?

I recently purchased a 2012 750li and I love everything about it but because it is a "luxury" car the exhaust is tuned so that you dont really hear the engine. I was on a budget so one of the first ways to fix this issue is straight piping, but I was wondering if it was too loud. What I mean by this is I want to hear the engine when I'm revving it but I still want it to be "drivable". Does anyone know if its too much and if so is there something else I could try?

Thanks.

I have the dinan exhaust and it is great, straight pipes will probably be really bad, and throw codes.

Jumping to full straight pipe from a completely stock exhaust will have a very dramatic effect. Try a muffler delete first, and if thatís not loud enough for you; consider a resonator delete OR a cat delete in addition to the muffler delete.
Just my two cents..

When I had first gotten my 540i it was too quiet for my liking. I had gotten a muffler delete a week later which helped a little bit, but it still was not loud enough. About another month later I deleted the resonator myself. I am overall very pleased with the sound and sound level of my exhaust with a muffler & resonator delete. It does drone a little bit but I am okay with that. Itís rowdy at WOT, but I can drive it somewhat quietly if I need to.

Which will give it just a tad more sound over stock, a muffler delete or resonator delete? I'm not looking for anything crazy loud.

In my case, the resonator delete made a bigger difference than the muffler delete did. The stock resonator that I had cut out was awfully large, so thatís probably why it made a big difference. My exhaust ďburblesĒ and backfires pretty loud sometimes.

In your case, I would choose to delete the resonator and keep the muffler if you donít want to be super loud.

In my opinion, my 745i was crazy loud without the exhaust system installed. I felt self conscious driving it when the exhaust was off. (Was working on it and took off the exhaust to get to the drive shaft.)
