It is very raspy above 3000rpm and screams like Gods private is trapped in a paper shredder.

Not much drone cruising in top gear 60-70mph. Its very normal. Only a bit more throaty when driving off gently compared to standard.

But I'm trying to cure the rasp... add resonator after x section or H section like akrapovic?
