So just like it says. I have an 88 gtu non turbo. I have a racing beat header, pre-silencer, and custom cat-back to an apex-i universal turbo app mufflers. But recently the neighbors have been complaining about the noise. I just discovered that apexi makes an ATS (active tail silencer) I wanna know if anyone has heard one of these in effect, or know if it would substantially quiet down the exhaust note at idle to lower rpms?

 

I have the ATS and it does quiet down the noise at idle alot, it sounds like crap but it does the job. I usually put it in through town so I don't get pulled over.
