Hey JRSC owners;
I installed the factory tuned C38 kit on my 2013 FRS about 3 weeks ago. I noticed from the get go that when I let off the throttle I hear a fluttering sound. Its more apparent at higher RPM. I took a sound clip and sent it to JR but didn't get feedback so I figured I'd take a video with my gopro mounted front centre of the hood so it would pick up the audio a bit better than in cabin and see what the community feedback might be.
At about 3:15 I come to an intersection and once I turn its much easier to hear as I come on/off the throttle around 3:30 - 3:50.
The beginning of the video might give some insight as well. I find the general low rpm operating noise to be pretty significant, I guess 'silent operation' means different things to different people? My car has a completely stock exhaust system.
Thanks
