Just installed the icebox on a bone stock 2000 gsr. I never would have believed that 170 dollars and 1 hour of labor could feel so good. This is the best thing i have ever done to a motor other than installing a cam or just rebuilding the damn thing!

the sound is perfect for anyone who likes the sleeper idea....but it still howls at Full Throttle! Thanks to everyone on the MULTIPLE threads who helped me out....i think i will recap the basics here so they are in one place.

Step#1 BUY Icebox ~170

Step#2 Ignore what comptech says:
you DONT have to buy the comptech shortram for the icebox to work.
you DONT have to buy a comptech filter for the icebox to work, stock fits fine.

Step#3 Dont order from www.imotorgear.com they dont keep a good inventory and delayed shipment like 5 times.

Step #4 Install it, you dont have to take bumper off, dont have to take tire off, just unbolt everything from under the hood and under the car and the resonator will fall out( i did have to jack the car up like 3 inches to get it out from under the car though
)

VIOLA! you have just gave you car some juice!
