Ehhh. Jon Boy is right with a couple of clarifications. The labarynth doesn't do much for sound, the sound wave splitting and cancellation does. The specific backpressure required is based on the cam profile.

 

yea you would think so. but theres really nothing i can do about it. or can i?

 

i agree with you 100% thats why i was asking for responses from other people.

cuz i honestly was expecting to lose power not gain power.

 

Just get the Spoon N1 and save the guesswork!

 

Hello, I'm a newbie with an 07. Where is the best place to get the HKS?

 

i got mine from invision

 

i have t1r 70mm and when i put it on the car started to misfire... is that somehow related to the exhaust?

 

So I guess everyone agrees that HKS does make you lose power? I mean I just don't get it. If that's the truth, why would all the vendors selling HKS give a nice paragraph of how HKS will offer greater flow due to less restrictive design? I know their intention of selling but c'mon... that'd just be plain lying. Again, I'm still not 100% sure if HKS does make you lose power. I love its sound and the only thing that's preventing me from buying it is because of this unsolved mystery.

 

Get one slightly used. There is one in the Bay Area FS forum. Good price.

Edit:

Here is another one, price shipped.

There are no dyno graphs to show it does loose power, only word of mouth. Basically, if you loose power, it won't be enough to notice. If you gain power, it also won't be enough to notice.

Vendors get the description from HKS. There is no one regulating the aftermarket, just look at the Tornado (pos). If it's a fear of power-loss, don't worry about it. If you like the sound, get it.
