Here's a question for a buddy. He's got a stock 89 convertible with a newly installed Vortech V3 making ~6-8 psi boost. He want's to know if he'll get more HP/$ if he installs a bigger throttle body and MAF, or opens up his stock exhaust (does have magnaflow mufflers, everything else is stock).
Which next exhaust or throttle body

Exhaust, no questions. On my 4.6L 2001 GT, I gained 36RWHP with an H-pipe and Cat-back. No tune either, I used MIL to shut off my light. Tuner said maybe another 5-8RWHP with tune, so I went the cheap route.
