Ben,
The gain of 36whp and 29wtq is huge for just swapping to a catless downpipe. Did you ru on a higher boost map as well to achieve this? maybe things have changed since I was modding my N55 but i don't recall a catless dp giving that much of a gain. Also how noticeable is the smell? Is there anything else on the market now that would suppress the catless CEL besides the JB4?
