The misnomer that the OEM manifolds are as restrictive as people wish to make them out to be.
Again - if the (many) variables are controlled that can add or subtract (easily) 20 HP/TQ on the dyno without(!) changing a blessed thing, and all those end-users out there who are buying (literally) into the purported gains found out just how small the gains (or losses) are...there would be a lot of pissed off people.
Remember each cylinder is firing sequentially...in the case of shortie headers the very same bottle neck just happens to be a foot or so further downstream when compared to OEM manifolds.
The same thing can be said about machined throttle bodies that retain the OEM actuating valve (no HP/TQ gains over the OEM units).
It really is unfortunate the amount of online BS that gets put forth as gospel (for example, dyno sheets) and the unspecting buyer ultimately gets taken...
As one of the first to get a dyno tune with a predator, I invested in Mopar Longtubes and hi-flo's...Sounded great..nada on the dyno...stock exhaust with a good cat-bac showed the same results, unless you are going to do engine surgery, headers are not needed..

Loved putting the Mopar LT's (Mid Really) on my 5.7 unfortunately never tested any actual differences...Hearing each cylinder fire the way tubes separate the sound and the overall tone change makes getting them so worth it IMO!! Plus the OEM mainifolds really are pathetic regardless how little they interfere with air flow - they should have at least done made em sexy like SRT did

I would go with a set of hi-flo cats and the Borla extreme or Corsa for the sound if you want to invest...

heres a question I been wondering, if I get headers for my 5.7 right now, and later upgrade to a 5.7 based 392 stroker, can I use those headers on that engine? Same question with heads really.. I'm gonna be in the market for a build motor soon and wantin to know what I can transfer over or what I'd need to sell.
