I recently purchased a FI stainless steel cat back system and I love it but I am thinking about getting there 300 cell High flow cats. I searched around but couldn't find exactly what I was looking for...

Can anyone post some sound or video clips of a 350Z with the Fast Intentions cat back and 300 Cell HFC? Thanks a lot I'd really appreciate it.

Bump...anyone???

 

I don't think it'll sound much different, but I can't be sure. I've swapped out a stock cat to HFC on other cars and couldn't tell a sound difference. Power, yes, sound, now.

 

makes a world of a difference sound wise on our cars. The exhaust will change dramatically with the addition of TPs or HFCs. No vid clip for you, try youtube.com or streetfire.net

 

I have these hfc's on my car-it made the sound louder but different from
usual vq sound-has a strange rattle and metallic tinny sound at
certain rpms-felt stronger after-smells bad like running rich when
driving behind the car

I disagree. Try paste white search up bolt around sneaker.

 

I wouldn't have doubted that TPs would make a difference, but I didn't realize that the HFC would change the note that much. Learn something every day.
