Awhile back I made a thread with a noise I was experiencing with my exhaust around 2.5k-3k rpms. I’ve come to the conclusion that this may be trumpeting. It almost sounds raspy or like a tick but goes away out of that rpm. I’ve tried multiple exhaust setups. I have an O/R X and two resonators currently. The two resonators I just changed to are twister race mufflers and my god they sound so deep and great at idle with the cams. I think I’m the only one that has put these on a s197. Anyway , the noise is still there but less pronounced than when I had two Jones turbine resonators. My resonators are mounted before the rear axle. The sound was gone completely when I had two magnaflow mufflers and the Jones turbine resonators but I didn’t like that “puff puff” of muffled sound of the magnaflows at idle. I like the deep tin canny sound. This sound is often heard in gear while giving it a medium amount of throttle. Does anyone else have this trumpeting sound? Can someone record what their exhaust sounds like INSIDE the car? The noise is only heard with the window open.
