Hi guys I just fitted the Super Sports exhaust a few days ago and I wanted to share some initial feedback for the community. My car is fitted with Fabspeed Headers and Fabspeed Sport Cats and the OEM Upper Y pipe. It was fitted with a Gen 1 Tubi which sounded nice, refined and very docile to drive but not very engaging to match the other cars I own. I wanted a bit more scream and drama since I love the way the F355 sounds with a nice loud exhaust. Also I will note my Exhaust bypass valve does work and I have done testing with it left connected and bypassed. The exhaust at start up is nice, has a nice rumble but once the engine warms up the drone inside the car is unbearable at 1000 RPM. This is with the bypass valve closed. With the bypass valve bypassed the drone maybe gets 5% better but its still there. I also notice drone around town in the 3000 RPM range then any input of the throttle from 3100 up to 6800 almost sounds stock then at 6900-8500 is screams like an old F1 car which I LOVE. The issue I am having is around town its getting annoying and seems to be pissing everyone off which does bother me in the village I reside. I wanted to throw this thread out there to ask you guys who many have been down this exhaust road many times already. Do you guys think the Fabspeed headers have anything to do with this drone I am experiencing? Would doing Test Pipes and a new Y Pipe change anything? The craftsmanship of the Nouvalari exhaust is incredible and for the money its a home run for sure. The fit and finish is equal to anything coming out of Germany for 3 times the price and now I know why these systems are favored with you guys. I posted many short videos on my Instagram page please head over and check those out over the last few days @autofanatic_cars The videos highlight the best part of the exhaust and that is the 7k-8500 range this engine and muffler seems to sing best. I will be doing a full video for my Youtube channel this week including some in car drone footage and sounds for guys to hear..
