There is the same vibrating on cold start with the Akra as OEM. Other than that, I am pleasantly surprised with the sound at idle and under light revs.
fan of the Akra in Sport Mode driving around town. So under say 6,000 RPMs the car sound really, really good. Revving the car in the garage sounds awesome. Above 6K, Akra and OEM make me cringe. I’m not sure anyone is going to be able to address the awful sound and farting the S55 makes at higher RPMs. I guess it’s good that it sounds worse in the car than outside.
I never, ever drive in Comfort mode but had a few people ask me to include some sound bites. It basically sounds like stock.
I’m pretty certain I won’t have this exhaust forever, but I like it enough to keep for a while.
