I have been in a car with the Stillen catback and berk hfc. It seemed to be pretty quiet when cruising but when you open it up it would make some noise which was nice! I'm thinking maybe the HKS catback WITHOUT hfc might be the way to keep the noise levels down IF the hks is indeed a loud exhaust.

So i was wondering if anyone in internetsland has heard/been in a car with the HKS and also a car with the stillen or FI catback. Could you give your opinion on both? e.g. in comparison of droning... noise levels ect.

Cheers guys!

I am surprised that no one has chimed in with thoughts. I really cannot comment on the HKS due to the fact that I have never heard one in person on a 370Z. What I can tell you is that I installed our TDX cat back on a 370 6MT this past Tuesday. It had our stainless steel mufflers and 18" resonators. He kept the stock cats on the car and I have to tell you it is the quietest one I have been in yet. This specific combination I had never heard until that day. If you like, please check out our exhaust here:

TDX CB LINK: Fast Intentions

Now the video on that page contains everything I am telling you about with the exception on 12" resonators. When we prototyped that version I felt it was quiet inside the car. Just keep in mind, the 18" version is even quieter.

I hope that this gives you some insight and if you have any questions, please do not hesitate to ask...

Thank you, Tony
