Currently i have a full HKS system with berk HFC's, but in this past month i managed to get 3 ticket's about my exhaust, is there any quieter hfc than berk's or should i just revert back to stock?

 

Motordyne claims that their ART test pipes make great power and are quiet. But they're expensive.

 

Have a look at this thread, I posed a question about cells and how they relate when finding a louder HFC vs a quieter HFC. Also, as you go softer in sound the hp also decreases... according to some that posted...

 

There are a few resonated HFCs out there. I think Invidia and Fast Intentions have that option. As far as cell counts, the sound difference won't be noticeable.

 

interesting !! so Invidia (100 cell) and F I (300 cell) considered as quietest HFC ?

 

buy resonated HFC from F.I

or wait for motoredyne to release their ART test pipes...

 

I have the Fast Intentions Resonated HFC and it is far quieter than the Berks I had on here before. FI is the only company (I know of) that makes a resonated HFC.

Also, if the Invidia really is a 100 Cell count HFC, whats the point? The 300 in the FI is low enough as it is so you might as well just go with test pipes.

 

keep in mind i have a HKS setup, to me its really loud and i'd like to tone it down, but i think ill look into the FI and the motordyne hfcs.

btw, whats the difference between a resonated and non resonated?

 

One has a resonator... The other doesn't....

 

This will tell you all you want to know about resonators.

the higher the cell the quieter
