Exhaust pipe material vs velocity
Tue, 30 Apr 2002 14:36:48 -0500
Recap- Smaller exhaust - better low end, torque, chokes at high end
Larger exhaust - better high end, loss of low end
Reason- Smaller diameter keeps exhaust velocity up but is flow
limited at high end
Larger diameter is not flow limited at high end but
slows exhaust velocity down from larger diameter
Question- Would using a more heat resistant material to keep the
heat in and thus the velocity up, allow a person to run
a slightly larger diameter exhaust without low end loss?
I am thinking 14 gauge Stainless 304 2.5" vs 16/18 gauge aluminized
2",2.25"? I will have S3s, HSgen4, CAI.
