Xtremeflow exhaust without cold air intake is 32 HP gain.
SMA exhaust is 28 HP gain.
Xtremeflow Power Flash is 30 HP increase
Predator Programmer is 20-30 HP gain.
These are all advertised gains. Do they make them up?
No I don't think so.
I know that the numbers Xtremeflow came up with where actual dyno number.
How much HP are you making with your Radix kit?
