Its the flowmasters that was for the 04 GTO's. Im running Kooks headers with kooks catted mids

hey breze, all dynos are diff. just cause yours red higher doesnt mean you actually make more hp.

[sgtcheech]

how much it cost you to dyno tune it?

What did it put down? (Before & After)

[jcash00]

at stock i had 293 rwhp/317 torque. and with the headers and flowmaster catback im at 323 rwhp / 337 torque.

Thats it??? I dyno'd 320.06 RWHP / 330.01 RWTQ, Bone Stock in my 04 M6 at Modern Muscle, When I decide to throw on headers & Good Tune i should be atleast around 345 -350RWHP or so. Nice ride just was thinking you should be putting out more than me stock
