1.5T Quick Invidia Q300 Exhaust Clip / Update with whining noise issue

imcrspy said:

All current and future exhausts are free of whistling noise. It was confirmed that it was a design flaw which was fixed. As far as I know everyone with the issue that contacted Invidia has had issues resolved already. The guys are cool AF. And a catback (which the Q300 is) will not throw a cel. It does nothing but make your exhaust a bit louder. There are no performance gains as far as I know.

This setup will not fit my civicx Si coupe will it?

Just installed the q300 on my fk7 today. I'll do a longer clip but wanted to do a quick recording so I could hear it. Hard to get a good listen when i'm driving it around haha.

Only mods are a Mishimoto intake and Ktuner v2 21 PSI map. Stock cat is still on.

So doing a full throttle pull onto the freeway, starting at about 2500 rpm and up, there's a fairly loud whining/whisteling noise. The car kinda sounds like it's supercharged and I never noticed any type of whine until the exhaust was installed. I've emailed Invidia to find out if this is a known issue or not.

Gordon from Invidia replied to my email. He was vague but stated that replacement mufflers would be available in 3-4 weeks and that he'd contact me when they came in. Also informed me that they would swap the muffler for me. Kind of annoyed right now after paying nearly $700 for the exhaust.

It's definitely loud with the downpipe, especially catless. I almost wish I went catted but it just sounds so good wot! The dash cam audio definitely doesn't capture the actual sounds of the exhaust.

Here's a vid when the I was still catted. It's louder than it seems in the video. With the DP it just got a lot deeper and louder.
