Are those numbers on a Dynojet 248? STD or SAE corrected.. What was the D/A and temp if STD? Smoothing factor plus 1?

I have the Corsa Extremes, Corsa X Pipe, Vararam on my Z06.

I dynoed at 372 to the wheels. The custom tune makes a lot more difference than anything else. Stock tune leaves a good bit on the table, about 10--15 horses.

Therefore figure the Vararam and XPipe/Exhaust were good for around 10 more, since stock is around 350-356 for 02-04 LS6.

That is a regular C5, not a Z. The Z exhaust are much lighter and better flowing. I speculate no HP increase but louder sound. Note I didn't say better but louder.

LT headers give better sound and more power.
