Not to be negative nancy but do those exhaust ports differ in size head to head or is that just the picture?
I see it too, even the shapes look different
2004 Comp G "The Panda"- low, e85, big brakes SOLD
2002 Trans Am- 6 speed, bolt ons or something, it's slow.
2006 Silverado- forged ls2, 4l80e, plate kit, also slow...
