Akrapovic releases catless downpipes for the S63 V8 in the X5M and X6M
S63 twin turbo V8 owners now have another downpipe options courtesy of Akrapovic. The piece itself is made out of stainless steel and is catless. No additional details were supplied. We would like to at the very least know the cost and claimed power gains. A dyno would definitely be warranted as well. Akrapovic makes quality exhaust pieces but without further details it makes for a very weak product unveiling. Akrapovic pieces tend to be expensive so do not expect this to be a value in S63 tuning.
