How did they improve the sound of the exhaust? How much louder did they made the exhaust sound? Thx

 

I would say they made the exhaust about 30% louder and with my setup I had no rasp. OEM headers, 3" y pipe, oem midpipe and custom muffler

 

I have got these same cats for my hr. they make it a little louder not much but smooth out exhaust. They are a nice upgrade over stock cats. I also have stillen headers and invidia Gemini catback exhaust.

 

I also have the same exhaust and im looking for some hfcs to make it louder, did the kinetix hfcs made the exhaust sound louder and better? Thx

 

yes it makes it louder. Like op said it makes it about 20-30% louder, but you might not notice as much since you have headers and invidia exhaust. i did all my exhaust at the same time so I noticed it being louder but it could be from other parts in the exhaust. You wont be disappointed with the Kinetix hfc.

 

bump! just to reconfirm since people seem to be confused. These are NOT the metallic kinetix cats which they currently list and sell for $380. These are ceramic core cats which across all brands typically sell from 450-500+.
