Headers and NPP

I have a NPP exhaust, instake and ported TB. Would I gain anything with headers and leaving he NPP setup?

I've got a new set of PFADT in the garage I'm taking in for ceramic coating this AM for my dry sump GS. Baselined @ 410 stock which I thought was high. I was expecting an honest 30-35 hp with a tune and headers, but I also have a new Tick spec'd cam in the garage too so I'm hoping to be looking at 50+ for a gain.

Of course. Don't let marketing fool you, catbacks and mufflers are 99.9% for sound.

yes but to get full gains you'll need a tune. Cold weather (40s) suckie for traction but you can see my MPH in my sig from headers/tune only as mods. It adds a bit of a punch and a hell of a lot of sound. I use the NPP exhaust.
