6.4L headers?

[F450twinturbo]

Does anyone offer headers or larger exhaust manifolds for the 6.4L

[Dusten]

not that i have seen, and the amount of work to install them would surely outweight the benefit

[F450twinturbo]

not to worryed about the install motor is out of truck and tore down. but if no one has any avalible then im s.o.l lol

i wonder how much headers would drop drive pressure? Might be worth it.

[F450twinturbo]

if it droped it enough it would be worth it even with my wastegate i still see backpreasure reach 84 psi. if i could find some i would definatly try them. elite offers ported stock manifolds but not sure if the help enough for the money they get for them. if anyone knows if they are worth it i would think about them but think headers would be more of a gain

What about getting them 'extrude honed' ?

[F450twinturbo]

i found someone that does extrude honing but was wondering if it was worth the money. to have them honed and coated they want nine hundred dollars, did not know if the honing would make enough diffferance to be worth the money? or is it? does anyone have any idea?

[H0USE]

porting and honing would be a good choice, good thing to keep the stock cast units, they are very strong.

[F450twinturbo]

I would like to keep the cast one just wasnt sure if the honing was worth the money or if i should just have them ceramic coated and call it good?

gotta watch for that bend at the end though. research I have done shows that 6.0 manifolds with custom up pipes is what rudys and those upper tier 6.4 guys run
