My lbz whistles pretty good with my silverline 4" on there. Haven't put an intake on there yet but soon.

You'll just have to keep the stock system for smog inspection. Careful with that Edge on 5. Your tranny won't like you. It's not a wastegate, it's vanes opening and closing. It's a variable vane turbo and the vanes open and close with the tuning. Get a dry filter. K&N's fluid will suck out of the filter and pulg up the MAF sensor.
