the fire birds always look it but the cd numbers never back it up. frontal area and how it puts the air back together off the rear window has the most effect. a pointy nose only looks better. so thats not it. i will say the 87-90 wing was better than the same years camaro, but they gave that up for the look from 91 and up.
unless the exhaust mod leaned it out a lot, im just going to call bs. im the king of hypermileing. haha,
Dont forget the Lid and filter...
