Mark,
Have you read TigersUnited's latest Gauge article (Restoration Tips),
and my latest post on cooling system mods. "So, How Hot Was It? The
information is also in TigersUnited Tech Tips, cooling section. I'll
send you another copy if it's been misplaced.
BTW, the Flowmaster "30" series are three chamber designs, not two.
They are 5 in thick x 10 " long, with minimum 2 1/2 tubing. Can be
attached to 2 inch with adapters. 2 1/4 tube is the largest size that
will fit through the stock frame tube, even squeezed, but they will bang
the frame on maneuvers unless you enlarge the frame tube like Larry did
in his TigersUnited Performance Tips Article. His are 2 1/2 inch tubes.
The louder "50" series come in a 2" inlet size, and are 4 in. thick by
9.75 wide 3 chamber.
The loudest "40" series are the 2 chamber design, also 4 in thick by
9.75 wide, and available down to 2 inch inlets.
Funny thing is the ones available with 2" inlet/outlets are more
expensive than the other sizes, even though the interior designs for
each series are identical, according to Flowmaster.
An "H" pipe will not only scavenge better, but smoothes out the sound
and adds a bit more quieting. Using Larry's flanged "H" pipe design
allows for engine, tranny work without yanking the exhaust system.
Another EXHAUSTING tip: The short stock Tiger's front rubber
connectors, between welded pipe strap and chassis eye, are subjected to
extreme loads on engine torque rocking. They do not last very long. The
same design, with shorter wrapped straps on the tube to lower the
connecting hole, and allow extending it to meet the floorboard eye with
four standard muffler shop steel-rubber-steel universal strap will allow
a lot of engine rocking on the mount without destroying the expensive
Rootes front rubber (which can just be left off.) The rear stock set-up
is OK, as the tips don't move very much (except on that speed bump ;-)
