Long story short, I have a X5 4.4 that has both rear silencers removed, with straight pipes in its place. Its WAY too loud. I'm looking to replace them with either something OEM, or close to OEM noise wise.

Any advice? I see the OEM parts are about 600 each. Any other alternatives?

Thanks

Just go to a good muffler shop and install some magnaflows.

You still have the large center muffler installed?
