pacesetter vs dc sports header

[s13silver]

i wondering what heaader would be better there both 4-2-1 header pacesetter header has a 1 1/2 primary tubes and the dc sport header has 1 5/8 primary tubes. What would be a better header. Im tinkin dc sport but want to make sur eits worth the $350 first and see if they ework for everyone?ka24de

Typically, my experience has been that a header on most Nissan engines is more of a hassle than it's worth. Leaks, poor fitment, heat, a MUCH louder exhaust note, etc. aren't worth a few horsepower to me.

The factory manifold actually flows pretty well. Ideally, a good straight-through resonated catback with a larger downpipe makes just as much (if not more) power on a naturally-aspirated KA.

If you must, they're both pretty decent, but nowhere near as good as the HotShot (no longer available). I'd lean towards the smaller primaries for street use.

Really depends on where you want your power band and other modifications.

I'd look into this one here. http://www.isisperformance.com/isis-per ... 4de-91-98/

Personally, I have a DC Sports header on my KA. What I noticed most about it was how it shifted the powerband up.

does anyone know what is the primaries tube size on this header and how is the fitment on this header? Good quaility isis 4-2-1 header

the one asoomal said to look into. ALso the only mods im runnin is header,hks hi power exhaust, and aem intake with a thermal intake gasket and upgraded cooling system and nismo engine mounts. just lookin for a good header thats good thanks

if i ran the pacesetter header that has smaller primariy tubes with bigger test pipe and my hks hi power 409 exhaust would that be better performance and street use? and daily?

[s13silver]

meaing the pacesetter header then test pipe that matches the collector which is a 2.5'' and then to match the hks hi power 409 exhasut. Would that be a good exhaust setup with header having a little smaller tube primaries?

I have no clue in the size of the primaries for the ISIS header, just e-mail them and ask.


It won't make much of a difference on a stock KA. Bolt ons do nothing really...so just pick whatever you can get your hands on.
