Thanks, I sized the Thrush alike... just have to weld on a 3hole flange and
a down turn tip and bolt it on with my "homemade deisel" muffler
'cradle'...mine tucks up between the bumper and the pulleys, across the
back... I configured the system to use specs for best torque, primary
header tubes at ~32" before joining at the muffler inlet.. Techtonic Tuning
spent lots of dyno time testing their performance systems for mostly inline
VW motors. They helped me with my Digifant 8 valve/ABA build.. I couldn't
be happier with the results... Though it sounds a bit too racy with the
Magnaflow....(PS... when I bought it it had a 6"glass pack right at a
deisel Vanagon manifold.... ugg
