If you want a high pitch wail right from the get go, then you go for a Dundun Racing, JCR or IPE exhaust. If you want a throaty deeper sound then Akrapovic is the answer. If you want the best of both then you got Armytrix.
Stock exhaust sounds better to me for the flyby. With the akrapovic exhaust sounds like those cheap non-sport cars that are fitted with a modified exhaust
im quite sure biesse racing know what they're doing but if there are 4 rollers spinning when testing a 2wd car then i believe the horsepower number will read less.
I'm sorry but this does not sound very nice, does not sound like a porsche engine/exhaust note. Maybe it sounds better in the flesh but not here. It is very difficult to get a 718 sounding any good with mods, must be the mid mount engine layout.
