i was wondering if anyone had these header on their evo? i guess the brand of these headers are Rev9 how are they? can they handle 20 psi?

 

Sorry can't help on quality however most all cheap manifolds have shown to crack in time. Though I have to say it looks more solid than the Megan or XS Power units most people buy. Those crack all the time.

If they offer a warranty though go for it and report back after some time. Boost will have nothing to do with it holding up really its more temp, heat cycling, material, and bracing that you need to worry about.

 

you buy cheap, you buy twice.

 

Pictures sure look great.

But I just watched this movie that had dinosaurs in it.. so...

 

lol just like those pictures of fast food. It never matches up.
