Exhaust gain

The only numbers I've seen from a company are the racing beat 58hp numbers for their full 3" turbo back and I'm confused why they're the only people advertising the gains. Everyone says to get the RB turbo back, but I was thinking of going RB downpipe into a high flow cat and something like a single HKS or Apexi exhaust. What would be the horsepower difference? Is there an advantage of going full turbo back or with seperate components?

You could use various components (3") and gain as much a/c the larger diameter. With the right combinations you don't even need the 3", but everyone jumps to the 3" for an easy gain in HP. along with only a few other parts eg, FCD, Flow pump upgrade.

Thanks - I was wondering if there was a cumulative gain by going all three inch instead of just 3 inch pieces --- now it's just finding 3" pieces... but I'm totally thinking HKS right now
