never layed my hands on some tti's but i know that the max wedge exhaust mans are heavier
then a set of hooker super comps. i do believe also that the original crossram intakes were made
from magnesium too. which is lighter then aluminum. not a 100% on mag use though.

383man there were a couple of dyno tests. the max mans were = to the headers for power making. the
exhaust that was standard on the max cars were tuned for it. the 3" pipe before the dumps was just
like collector extensions used today. i believe the max wedge cars destine for SS use came with
a single exhaust. IIRC. therefore i think thats where the "header makes more power" theory came from.
