Upgrade Your C4 with a New Power-Flo Exhaust
System
C4 owners, we haven’t forgotten about you. Bolt on a
Power-Flo™ catalyst-back exhaust system on your LT1, LT4, or LT5-equipped ZR1
Corvette for up to 5% extra horsepower with a low, musclecar rumble. The tone is
a little louder than stock to let everyone know you’re coming, but not
obnoxiously loud to keep your Corvette somewhat civilized. Our engineers
developed this system to sound great on the street, but minimized interior cabin
resonance. This system features a pair of distinctive stainless steel tips, is
hand-crafted from 304 stainless steel, and is covered with our Limited Lifetime
Warranty.
