After three NSX and exhausts by Tubi, ARK, GT-Rom, a Custom one and listening to a few others, I had an epiphany; I do not need one exhaust! I need two exhausts. So I designed a system that can be change in 10 minutes. I have two exhaust now, one that goes from raspy and nice ( tubi loud ) at idle and high pitched at high rpms ( Gruppe M - GT-Rom F1 ) and one loud that surprised even Amo!
Here are the videos, enjoy!
