I have used the Monza system. Its cheap and adequate. Alternatively,
IMHO use a header (stainless), primary diameters are dependent on your
engine mods, wrap the header in tape (saves heat and starters,), put the
oxygen sensor behind the header in the main pipe, - recommend single 2.5
or 2.75 inch back to a Borla exhaust dumping out a single 3 inch pipe.
This would have to be custom built. Nice part is that we don't have to
worry about the catalyst stuff.
That will make a very large difference at high RPMs while you may lose
some bottom end torque. Trick is to remember the engine is an air pump
and match up the capacities of the front (carbs & intake), middle
(pistons, compression, and valves), with the end (header, pipes, and
muffler) to get the most positive impact from each mod.
