@DoubleDingo and @Catbox I actually got a sweet custom set of shorty headers for this 455 (exact exit position as stock manifolds), and a pair of 3" electric cutouts.
So, with that being said this truck already had long ass smitty brand mufflers on it, so I want to see what they sound like!
You mention looong glass packs, my dad put a set of 42" long ones on his beautiful 78 Trailering Special Suburban, 454, holy balls did that sound mellow until you really got on it!
