HP gain from exhaust on C5?
I dyno-tested the cutout on my 99 z28 and with a pulley also, went from 297rwhp to 323. A nice gain.
Now, I'm about to install a Borla Stinger along with the crossover Xpipe. Will I see similar gains?? Is it purely a sound difference? THX!
The X pipe gives the Vette's a nice "scream"
For a "muscle car," the vette sounds wayyyy too tame in stock form.
