hp gain after these mods?
What should i expect to put down after a ls6 intake, kooks 1 3/4 headers, the kooks 3x3 off road x pype, BB cat back on a 99 frc 75k miles, M6 car.
Would a vararam intake add a difference on the dyno? im debating on weather to get the intake before or after the tune. Should a vararam require a tune?

Vararam won't need a retune and won't make much of a difference on the dyno, however at speed they are the best bang for the buck.
All those mods with a tune are worth I'd say 25-35 HP, maybe a bit more if your base tune is way off. Starting off with 310 should net you 335 to 345, at the tires of course.

Should be able to get that, the Vararam is worth a bunch but not on the dyno. I ran many runs without it and my first 4 with the Vararam were all faster. I don't remember the exact numbers but those 4 averaged around 2 tenths and 3 mph better than my best runs without.
Good luck!
