Spring rates on the Tanabes are 10K F and 8K R.

thx.

im going to try to install her right now with no air tools :-p

very nice congrats its going to be loud

You'll be amazed at the difference in the sound. Expect your gas mileage to go down dramatically for the next 2 tanks as you'll have a hard time keeping your foot out of the throttle.

Try to find a tunnel or parking garage to go through. You won't be able to stop from ear to ear.

drool on that hks! you get a good price?

very nice pick up on the hks

Veeeery nice. HKS is awesome i looove mine.

great pick up. I <3 mine.

Oooh shiny!

An HKS is high up on my list of things to get. Let us know how the install goes and how you like it.

Is it really that loud? The vids I've seen don't seem too different than stock.

HR Y pipe, Coupe middy, and HKS sounds the BEST.

Except for the irritating drone between 1500 and 2500 RPMs. Outside of that the sound is pure sexx!!

My stickers just arrived. Big thanks to Elvis from Stance:Nation for designing these for me and hooking me up with his sticker guy.

Got them made in silver, white, chrome (super limited), and reflective gold (super limited).

^Those like classy, I like.
