hey i might pick this up soon but what would you recommend me picking up along with it?

 

cats

 

Plenum spacer

(edit on the rest of my post, was thinking of the sedan HKS)

 

would helix high flow cats be a good combination with the hks hi power?

 

Twin Turbos

 

Extremely nice choice!!!

 

If you get the HKS exhaust you'll only realize it's potential if you add a 5/16"
spacer (MotorDyne) and the intake/Z-tube combo. You can do the cats at
a later time but the above mentioned mods will make a major difference in how
well you G moves/sounds. Unless you live in Florida removing/replacing the
cats is illegal....if you care!

 

^ whats good a good intake/ ztube combo?

 

stillen hi-flo intake box + z-tube
jwt popcharger + z-tube

 

^thanks a bunch.

 

Yes, definitely opt for a MD plenum spacer and/or Z tube combo of some sort. Have fun and enjoy!

Edit: Actually, what model year is your G and does it come equipped with the 6MT?

 

i have a 5AT '06 coupe

 

You guys think adding a 5/16 makes that much of a difference to a HKS exhaust, and why?

It just sounds better then anything :P

 

Okay then, for starters, you might opt for either the Motordyne 5/16" or 1/2" plenum spacer in combination with either a Z tube complimented with either a drop-in filter or a JWT popcharger. I like the Stillen Hi-Flow Air Box option, but it will cost you a bit more.

Btw . . . You will absolutely love the HKS Hi-Power Ti exhaust, if you end up getting it.

Here's the link to MD for ya.

^ thanks a lottt, do you know a good site to get a stillen hi-flow air box? and with that do i need a z tube as well? and i am going to get the hks today thanks!

oh and if i get the 1/2 it will fit in my coupe correct? but the engine cover won't go on?
