If you want loud, the BMW performance exhaust may disappoint. The BMW perf exhaust has a great sound but it is only slightly louder than stock. The change (and value) is more in the tone.

The berk race will be considerably louder and has a good aggressive tone to it. It is also a lot cheaper than the bmw performance exhaust. It should not violate your warranty in anyway.
