I've had my ST1 for a little over a week now, and I noticed that the engine was unusually quiet. I had a sound symposer tube in my '12 mustang, so I am familiar with what it's supposed to sound like. The mustang sound tube wasn't actuated by a valve, it was just a simple mechanical thing, but it worked. The ST has always been dead silent since I picked it up
After driving my buddy's ST, i noticed his ST had much more growl under load, so i thought hmm, maybe my sound symposer isn't working correctly. I just ignored it and kept driving.
Then, I was driving around tonight, and i notice that the symposer was actually opening under load today, and I could totally tell the difference, it sounded great! After a couple miles, I noticed my intake noise was much louder, all the time, not just under load. I came to a stop light and i could hear the engine loping inside the cabin, and I know it was sound symposer. At first I thought maybe my Green filter came loose or something, causing the extra intake resonance, but no...I popped the hood when I got home and the filter was fine.
I started the car again, and the inside of the cabin was filled with intake sound, even at idle. It's pretty loud. I shut the car off and noticed a beeping noise, like an electronic fault error beep on a motherboard. It beeped four or five times, then i heard a mechanical click, it sounded like a plastic door shutting. I'm assuming after I shut the car off, it went beep, beep, beep, beep, and then shut the symposer valve.
Because I'm 99% sure this is the symposer acting goofy, i'm not afraid of anything being damaged or anything, it's just kinda weird.
Any thoughts???
