Forgive me if this has been covered and please point me somewhere else. I just got a 360 with a Tubi exhaust and the sound level is too high for my liking. Is there an alternative system that's quieter without going back to stock ? Hopefully one that will not kick off lights.
Tubi does produce a more quiet version for the Swiss market. That's one possibility. Another thing to double check is to make sure the secondary air valve isn't in the stuck open position. That can produce a very annoying drone to the Tubi - or any exhaust. The best method is to clear the ECU when the car is cold. That will reset things as far as the air valve stuff goes (as far as I know and as far as my experience has been). The other thing is to just drive the car for a while. With my car, when I first installed the tubi and hyper flow cats, I found it to be a bit on the loud side. However, after driving it for a while, I got to like the sound. The other thing is that lower RPM's will make the Tubi sound louder. Sometimes down shifting will kick up the RPM's and produce a slightly lower exhaust note. Ray
