I turned the car on and left it running for about ten minutes and this soot was produced. Is this a normal amount? Given I have a deleted interior is this stuff coming into the cabin and should I be breathing it? The stripe at the beginning is where I scraped it with my foot to determine the consistency. It was smearable as opposed to purely dry.

not normal. some water is normal (look up hydrocarbon oxidation reaction)

Many of us catless 951 owners have learned to avoid walking behind a cold 951 for this very reason... While it looks to be a bit, mine has spewed a similar amount of fuel/oil/moisture while warming up for going on 8 years with no ill effects.

Looked it up, seems like a malfunctioning catalytic converter ... what's the harm? I was thinking of splurging and getting a 3" cat bypass exhaust

the harm is to those with lungs who anticipate breathing - and depending on your state, the additional harm may be to your wallet if you modify mandatory pollution control features. The first is up to your conscience, the second is up to your willingness to take risks.

I remember backing into a buddy's driveway and starting mine up against his closed garage door. SPLAT!!

I may just bite the bullet and get the the Lind$ey exhaust with a new cat and better sounding muffler
