Well, I called them today. First off, they seemed to have found paint at Pep Boys similar to my body color in matte that they wanted to do a little trial to see if it will look good, but after my phone call, I sent them a text back and told them just to go to a paint supply store, get WW1 PPG paint and do it right once (which they've been telling me about everything else).
This was also the next big thing I talked to them about. The Flowmaster exhaust has been CANCELED! THANK GOD! I'm not a huge fan of them and ironically neither is the build manager. I walked him through TTi's website over the phone and showed him exactly what part numbers to ask about when he calls them. I also showed him the information for which starter to get that would fit with my TTi shorty headers. So, yes, the entire exhaust, headers to tips will be TTi with the Dynomax mufflers. We'll probably go with 2.5" for rooms sake and we're unsure whether it will be an X or H pipe due to the trans. I think 3" will be overkill based off of what I read: http://www.exhaustvideos.com/faq/how-to-calculate-muffler-size-pipe-diameter/
