in the search for more low end from my under powered over weighted car, i am wondering about a set of flowmaster 4 into 2 into 1 collectors.
the original collectors are 8" x 2 3/4 ID. the flowmasters are;
effective length 22", 2" of 1 5/8", 11" of intermediate and 11 1/2" of 2 5/8".
my current RPM range is 5200-7000. cam is 240/250 @ 50
thoughts?
thanks rod
