ok I just did the snorkel mod.

My girlfriend was convinced that it wouldnt add any sound to the car.

Afterwards she was proven wrong!!!!

She admits the car does sound admirably louder. And if you look at the snorkel from where the air enters it, that cup blocks 30-40% of the air coming straight in , the air would have to go up and over the cup, also the snorkel iteself ovbiously takes up space in the intake tube, so that would be less air in there, which would equate less horsepower.

I did the modification to my 99' Box and I am quite impressed. It is noticeably louder after 3k RPM. It does have more pickup after the modification; at least that's my experience.

This website has a very good "how to" de-snorkel:

A couple of points:
1) When removing the snorkel I grabbed it and gave a quick hard yank, it came out immediately.

2) Make sure you push on the slats in the correct locations. That was the hardest part for me.

I've seen the tray that you mentioned on a 97 model, but my snorkel doesn't have a tray at the end. I would imagine cars without the tray wouldn't benefit as much from a desnork for the reasons you mentioned above. Does anyone know when they did away with the tray? My guess would be 03, but I'm not certain.
