Racing Beat claims that it will give you 59 horses. Thats whats on my t2 and its because there is no cat. Also when buying the exhaust you will need to get a fuel cut defencer because if you dont, fuel will not go to the rear rotor because of the higher boost this exhaust allows.

due to the face that this exhaust causes ummmm boost creep you could say the stock limit on the turboII if im correct is 10psi well the racing beat fuel cut defenser (FCD) allows you to boost more than 10psi but if you dont install this fuel stops going into the rear rotor when the computer senses the motor receiving more than 10 pounds... so to really notice the power in this exhaust system you would need the Racing Beat FCD and the Racing Beat Exhaust

If you dont upgrade your wastegate and have a exhaust, such as a RB, your boost will creep up. the ECU will start cutting fuel to the rear rotor once i reaches a certain psi. then you go kaboom.thats why you need a fuel cut defencer.

stock psi on an S4 TII is 6.2 PSI. you will hit fuel cut around 8.5 PSI. this is only from what i have read on the forum so if im wrong...blame those fools over there

stock boost is 5.5 and 7.5 on S4s and S5s respectivly. just memorize ReTed's website and all you noobs will know everything it's an amazing site.
as for the turbo back, I have one, it's deffinitly a really awesome exhaust. I'm not sure how much hp you can expect, I replaced my stock exhaust which had clogged cats but it's a good bit

Most of the gain is not simply from the boost increase. At stock boost with a 2.5" single exhaust my car made an extra 30hp+. It stands to reason that a properly designed 3" exhaust should gain even more. http://www.geocities.com/jeffguilfoil/dynoresults.html
