Dougs or TTI Headers?

This thread started with which is better - but the responses have been which fit better. I have TTis - they fit ok - but on the dyno they were pretty bad. May just be my set-up or something unique .. but we tried other headers (many of which would not fit in an a-body) and those that had longer primaries and/or longer collectors did much better.

Anyone do a Doug/TTi HP compare?
