Dnp or fp

[streby50]

Which manifold is better a dnp or the fp cast?

Depends really if you want a manifold wastegate ir not, and if you are worried about under hood temps. I use the dnp and love it.

I'm running the fp 3575 so I don't need a waste gate on the mani I just want to make sure the dnp won't crack on me and what flows better?

IME the FP race manifold flows better.

The FP manifold is also cast and therefore extremely resistant to cracking. The DNP manifold is tubular and not exactly indestructible.

The FP would be more than good enough.

Btw, ive had my dnp over a year no cracks and 10k harsh low timing miles. No issues. I'm switching to stm t3 though. The good thing about the FP is that you can easily put a heat shield over it. I'd think tubular longer runners would flow better because the fp has a similar to stock design but then again i havent owned the fp

If you do get the dnp and wanna keep it nice, dont touch it with your fingers, and if you do, use acetone before you run it. Or else that nice polish will turn to burnt crap look. If you don't touch it it will keep a nice shiny gold look. The DNP is a very good quality piece IMO and has extremely good welds.

This is with my scm6152 when i first installed the manifold.


And 8k later after scotch briteing it thinking that would bring back the polish from when i touched it with my fingers.
That was taken while installing the shep trans and hx40
