Catback Exhaust Question

Thinking about installing the catback at some point (maybe) but was wondering if it is necessary or recommended to re-tune the vehilce after it's installed? I'm assuing there would be a change in backpressure and therefore could affect MPG? Any thoughts and or experiences?

No retune is need just for that. However the piggy, intake, pulley and catback will complement each other nicely. I know it sounds like an upsell but it is true! Thanks

What kind of HP gain can be had from installing the Cat back exaust after doing the piggy and SRI mod?
I don't want my car to sound all japped out unless it really picks up the engine.

I'm skeptical how much a cat-back exhaust would really do. Unless you are replacing the stock cat with a high-flow version, wider-diameter pipes won't do anything since our cars are hardly experiencing any back-flow problems.
Please correct me if i'm wrong, or if the cat-back exhaust corrects any deficiencies in the stock system.
