Does the akrapovic titanium exhaust system need a heat shield?
I noticed that the stock exhaust for the e92 m3 has a heat shield near the differential. I have also seen that the eisenmann exhaust also has a heat shield in the same area. However, I noticed that the akrapovic exhaust does not have a heat shield, and I was curious to know if installing a heat shield around the titanium piping of the akra provides any benefit. Anyone have any idea?
