My 2 cents.
On my other 4 banger, the Italian job, I changed from a 4-2-1 race header with
a 2" exhaust to a 4 - 1 equal length race header into a collector with a 2.5"
exhaust. I noticed a hugh increase in low and mid range torque but not really
a difference at the high end. The most notable difference is.... It sounds
really cool.
