I just installed some resonated test pipes from Ichiba on my car today and I was a little worried because I was unable to find any info whatsoever on these. I am posting a short video I took after the install for those who are trying to find info on these and for some opinions. I am undecided if I like the sound yet. They do make the hissing sound but I hear that replacing the stock Y pipe can resolve that? Well anyway here it is. Opinions/ suggestions please, good and bad I don't care whatever you can give me. Thanks!

Sounds really good. I can hear the hissing, but just barely. Is it worse in person?

sounds good, I think FI HFC sound better IMO

You can hear the hissing a little more in the cab but only with the windows down. behind the car the sound of the exhaust covers it up. I ordered a new Y pipe though so once I get that one hopefully that will help it out a little more. I heard the hissing is cause by the stock Y pipe mostly. not sure how true that is, guess I'll find out.

hey so what exhaust are you running on your ichiba resonated test pipes? i am about to install them on my car and i have a stillen exhaust on it. hopiing i dont dont any hissing ...

I have these installed too on a stock exhaust hear that hissing noise like its about to spool up or something on acceleration lol

idk...mines were cracked and got em' rewelded but i think they are cracked again so it sounds different on different starts up, like sometimes i'd start up the car and it'll be a deep sounding exhaust or most of the time it'll be like raspy with rattly hissing noise which i hate =[
