To each their own, I'm not one to knock another man's personal preference. But out of curiosity, what don't you like about headers? The way they look or something? I understand someone liking flowmasters over glasspacks or 2.5" over 3" etc, but I can't figure what's not to like about headers? As I said, not trying to start something, really just want to hear what you don't like about them, maybe there's something I never thought of (besides maybe not being smog compliant, but **** all that lol).

Also, for the record I don't have headers on my truck so I'm not trying to defend them or anything. Hah I didn't want to waste the money when I have so many more important things to work on first, but I definitely plan to get some when I build the new engine
I've had headers thru the years, beside lossening bolts,frequent burned out gaskets,and rust and heat....what's not to like about headers.Lol

Rust is certainly a legit gripe. As far as the other stuff goes, good quality gaskets make the difference. Once the bolts are torqued down the second time (after several heat cycles) then everything stays put for years to come with no leaks. Until they rust out and you have to do it all over again, lol.

Factory manifolds...install'em and forget'em. When I run across a square body with headers and/ or a Holley I move on.Unless I'm buying it for the tranny or body parts.I have a 13 Ram truck and folks are always talking about putting headers on theirs.It's okay if that is what one wants to do but I retired from header use and installs so never again. Now on my chevy I wouldnt mind a set of ramhorn exhaust manifolds. To me headers and what you get out of them is no longer worth it but I'm a grouchy old dude now and a bit lazy.lol. For me 2.5"pipes/flowmasters and duals are good enough for a old slow mid 1970s 350 engine.

Eddie,you've never seen a cracked sbc manifold?? It's hard to forget til they get warmed up...LOL
Ive owned around fifty cars and trucks and never had a cracked one but it can happen. Still rather have a cracked manifold than a leaking,rusted burned out overpriced header! Cant make me love the headers! Lol
