Ceramic Cat vs. 100 cell Metal Substrate Cat
Also if some of you have spare stock cat shields, you can fit this cat under the stock shield and look really stealth. I have the bare cat and when you blow through it, it feels ALMOST like you were blow at your hand with no cat in front. Found some pics for you guys look

^^Yes, an ingenious SoCalEvo.Net member did that himself using a donor testpipe and our universal 3" 100 cell cat. That's how I constructed mine as well 
However, our bolt-on units will be fully TIG welded, completely stainless steel including flanges and entirely polished.
There is no other race cat in the market that can match the flow of this 100 cell unit. All other race cats that we've seen are 300 cell.

Hey razorlab, where is the additional power coming from in parts of the curve where the revised boost curve matches the original boost curve? More timing? Revised afr?

More flow overall, some added timing. AFR's where pretty close to each other if I recall.
