I currently run open pacesetter longtubes on my LT1, mods in the sig. Ignoring sound or any other factor not related to power, am I gaining more with no exhaust, or would a true dual, or any sort of catback system help? Remember, I don't have cut-outs, it's just straight out of the headers, no pipes.
