It's important to note that the 4.8is mufflers are MUCH louder than the 4.6 mufflers (which are the same as the 3.0i mufflers, except for the tips). If you want some extra noise for low effort, that's probably your best bet. I believe that the 4.4 N62 mufflers are the same, but don't know that for certain.

I suppose, not really feeling like it would make a huge difference tbh on a v6, my theory was smaller mufflers and possibly more stainless steel options but I could be wrong, such a shame they made the v6 so silent

The I6 is anything but silent, trust me on that. With cats and stock mufflers the sound will definitely be deadened.

I’ve been told I can be heard miles from said listening location LoL.. Try and find super small straight through design aftermarket mufflers. It’s your best shot.

I have 4.8 mufflers on my 3.0 and the noise difference is dramatic. To the point where non-car people notice. Combined with your resonator delete, it'll make a real difference.

I referred to this thread when looking at all options and heard the sound clip, didn't really make a huge difference than how mine currently sounds but I'll keep a lookout for any 4.8 ones for sale

"mrbmwx5 has put 4.8is mufflers(left and right), each of the muffler is list priced at $819.40(see link below). If you are buying these from dealer, it will cost you over $1600 +labor. You still will not have as good sound as you will with Eisenmann or Remus mufflers for less price. Unless you can get some used mufflers, its not worth it"

Or you could get something like this..

I am positive you’ll hear a difference with 2 of these. And the muffler body is only 12”. Might work. :dunno:

I paid $150 for mine. X5 parts are cheap.

was leaning towards something like this, I know it won't sound ideal but I already have a similiar setup

That is pretty much what I’ve been suggesting. The 3.0 will have a different tone compared to the 4.6, but it will definitely have a stronger tone than the stock mufflers you have installed currently.

If you’re looking for sound, this is the right path.
