Charcoal Filter Delete

I took on a mini-project to remove the charcoal filters. I'm in what may be an endless pursuit to maximize induction noise. I figure that if our forced induction cars sacrifice that great sound of a normally aspirated car, I might as well hear more turbo-ie noises. My tune was by far the biggest contributor to increased induction noise - perhaps by +50% since I couldn't quite hear it before with the windows up. After removing the charcoal filters, which exist for emissions purposes, I gained another +10% or so. For a free mod, it's a no brainer if you dig induction noise.

The process is very simple. On a difficulty scale from 1-10, I'd say it is a 1 or 2. There is really no difficult part in the process and it takes roughly 30-45 minutes if you're in no rush and just enjoying the process (plus taking pictures).
