Do YOU GUYS HEAR ANY HISS OR RASP? ARK PERFORMANCE INC HFC PROTOTYPE INSIDE
After 2 weeks with this car.
Taking on and off the HFC's for tests (We owned the demon bolt x8)
Testing various Type 2 and Type 1 setups
Calculating frequency
Calculating exhaust gas temp
Calculating the velocity of the exhaust gas
Measuring the length of our HFC

We have done what no other company accomplished since the VQ first debuted with the G35/350z.

The main task at hand was eliminating the rasp and hiss caused by Testpipes and HFC's.

The video below shows some revs with AEM cold air intake + ARK HFC Prototype + ARK Type 2 v2 Exhaust prototype.

We will release the finalized photos of our HFC when its in full production. This is because we are sure that other manufacturers will eventually copy our design.

Sounds great! But Aggieav8r is right, take it out on the street and you'll find out whether it has rasp in the high rpm's..

lol Not trying to bash here.. but I find above statement to be pretty funny b/c basically your exhaust is a copy of the HKS design. I hope you guys did something original with the HFC design.

Hks has nothing on this ... I have owned both and the hks is garbage and cannot even compare .. If they truly eliminate the hiss and rasp it's going to be tuff to beat this exhaust...

Both are quality systems. As mentioned above, I am in no way bashing ARK. All I was saying was that HKS was the first manufacturer of the dual chamber system.

BTW can you explain what makes the HKS "garbage"?

I think what he was referring to was the price of the HKS that does not compare to what ARK has to offer. As for the dual chambers( Helmholtz pipe). HKS is not the first company to utilize this.

Atleast they manage to have great fitment and balanced mufflers, unlike ARK that got one muffler lower than the other..
