Also if you were to convert your exhaust system to the one that must be
on the r/t whichmust have dual cats and no crossover pipe how much
backpressure would that relieve.
I am sure it would be possable to put an r/t exhaust system on a 318
because I bet they
use the same manifold/headers on both engines. Both engines look the
same on the outside!
I am told they are the same except for bore and stroke.
