Want to get kinetix high flow cats. I currently have the nismo headers and nismo catback. If i put the Kinetix HFC's on, will my car be really loud or will they not make that much of a diffrence?? All the sites i have looked on say they will be a little louder.

Anyone have these and know what they are like??

 

i guess it's a nice combo in terms of sound. still it won't be as loud as tps

 

They don't really make that much of a diffrence in terms of sound. I have some if you want them.

 

I have Kinetix HFC's with a Nismo cat back, and its not SUPER loud, but I dont have headers either. I LOVE the sound of the Nismo with the HFC's. Its only louder when you get on it, and are around the 3000rpm range, then it kind of quiets down a little. I recommend it.
