Pure power go for Motordyne or if you don't want that you might as well go X02 if you only care about power, it makes the same as HKS and is a lot cheaper. But really your gains are so small you better love the way your exhaust sounds and like the look if you are going to even bother changing it.

Motordyne

I've said this before and will say it again...

Someone show me a dyno proving gains with the HKS.

Example, Motordyne.

To the OP, I'd spend a few hundred more for Motordyne. It's made in the US, excellent service, and the owner posts here on the forums. You have the ability to choose from different configurations, run test pipes WITH a HFC and most of all, dyno proven.

Damn u Motordyne. Super expensive set up aggghhhhhhhh.... XOS hhhmmm maybe.

Motordyne

I would say HKS or MD.

if too expensive then............................. SAVE UP!! don't waste your money on cheaper stuff and end up saying this "aw crap, why the f*** did i just get this? it sounds like a bicycle with a hug bottle stuck to the tire..."

X02 has been dyno proven and since the design was taken from hks essentially, you can argue it makes equivalent gains. I'm not saying it makes more than MD, but for the lack of substantial difference in power you might as well choose hks if you like the sound of it much more than MD.

^ How much power does the x02 make and on which dyno? Just curious

scroll down to post 37 or so. If I remember correctly there are another few threads with dynos on here or my350z but I don't have them saved...

Oh I remember reading that thread before. Thanks.

Yeah I know, that was me that posted the dyno in that thread so I know it makes gains. The point I was trying to make is...to prove the gains of the HKS over Motordyne. Still, to this day, nobody has posted an actual dyno of the authentic HKS but people still claim that it makes gains without solid proof. I wouldn't use the posted X02 dyno as an acceptable dyno for the HKS. The X02 uses different diameter piping, has a useless H-pipe with a 1/2 hole and obviously, different resonators and mufflers.

MotorDyne > HKS > Fast Intentions

agree completely. those would be my top 3 choices in order.

maybe even.....
MotorDyne > HKS ≥ Fast Intentions

hell if i could buy all three and switch around that would be awesome lol
