Default 04 CTS-V LS6 with Kooks Longtubes 387 SAE RWHP!

Here is my daily driver CTS-V. just finished up the header install, and am quite impressed with the results.
Here is the comparison from the last dyno session, which mods consisted of a K&N intake kit, Flowmaster mufflers, and a custom tune.

New mods include
Hendrix Engineering clutch kit
Spec steel 24 pound flywheel
Kooks 1 7/8" longtubes with off road connection pipes to the stock catback
Retuned

I am impressed!

Do a little more tuning...is the tb ported? Your about 26rwhp off of what my crate ls6 does....no reason you should be able to atleast get closer than that. You should make 400+rwhp
