I have no dyno results to support the fact that HKS loses hp. All I can tell you is that I have heard from too many people that this is the truth. A very trusted friend was at a dyno pull of an 02 S that lost 15 hp when the HKS was bolted up. To be sure, they did another pull after reinstaling the Stock unit and, wow, the 15 hp came back. That is an eye opener. Sorry, but sometimes you just have to believe it when you keep hearing it. My philosophy is why take the chance.

 

Best advice....go to a meet and hear for yourself.

Invidia is an aquired taste. It is a quality piece. WOT sound is exotic. If you are not conditioned to the drone at cruise it will litterally give you a serious headache.

HKS...awesome sound, no droning at all, looks great. I've been in both cars many times with these setups and this is what I've learned. Only downside to the HKS is it is made of steel, and has been know to rust out. If you avoid road salt it would help alot.

Don't expect noticeable HP gains from either...less weight, sound and nicer quality are your only gains.

 

everyone keeps talking about how it sounds like the F1 car with the Invidia....but it sounds pretty deep from the sound clips and most F1 cars are pretty high pitched...more of an ITB sound

 

Is there an Invidia single that has the same F1 car sound and make power??? If so, i bet that would sell alot.

 

HKS all the way!

 

way too many stories about HKS losing power.......so if i were you..........NO...but that is being bias of course and without much evidence...but I just don't want to take a chance.........so i got the AMUSE...

 

Does Invidia make single or it is all duce duce. I was thinking going single, I guess it would not be too hart to make a single out of a duce system.

 

Should try T1R Sparrow

-high quality sound (no droning/ not loud)
-high quality made
-good performance gain

 

where can you get the t1R sparrow?

 

Again, prove this with dyno results.
