header question

what's better for nos a 4-1 or 4-2-1? i would assume 4-1 since it's better for the jrsc.

Since your not boosting as much as the JRSC, I would say that your better off with the 4-2-1. Your engine will respond much better when not breathing the funny stuff.

I would say don't sacrifice any driveability for something that makes a few more ponies on the bottle. You can always step your shot up if you want to make more power. You aren't always spraying and that is what is nice about n2o, the power is there when you want it. Go with a 4-2-1 like wreck said.

On a side note wouldn't a 4-2-1 run on n2o better anyways? I mean, you aren't forcing air in the combustion chamber, you are just giving it "enhanced" air so you wouldn't have that much exhaust, right?

does 4-1 slow your car down that much?

you aren't going to have much back pressure, so it would be like running a 3 1/2" exhaust from the block back.

I thought 4-1 headers were more low end power and less high end, and 4-2-1 were reverse? Or is it the other way around.

4-1 are for better low end and 4-2-1 are better for mid and top end power.

are you sure? I thought 4-1 headers were more free flowing and that is why they work best on FI cars. If that is the case then you wouldn't have as much backpressure as a 4-2-1 header.

Sorry Mugen, you're wrong

The 4-1 headers would kill the low end power. Their good for auto X cars that would stay in high RPM's for a long time. Probably good for supercharged cars also. Kamikaze is the only 4-1 that I know of for the lude and I've heard some bad stories about them.

For daily driving, he'd want 4-2-1 header because they improve midrange power.

I don't think any header will really improve low end much, but the 4-2-1 won't decrease it as much as the 4-1.

I heard that a SS header saves 30 lbs on a fifth gen.

tha's enough to make it worth it to me.

I think a CF hood only saves 20 lbs, and that is a big weight savings. your header doesn't weigh anywhere near 30 lbs. It probably weighs 13 lbs or so, and you aren't going to lose much by going to an SS header.

You sure a stock Header is only 13lbs. i heard it was cast iron and weighed a ton. I've never had it off my car so I only have second hand knowledge but if it's only 13 then cross a header off my WISH list bringing the NX kit to the very top of the list

It looks like it is mandrel bent steel piping, not anything heavy. I just guessed on the 13 lbs, but I bet I'm close. The stock header looks like a DC one or a Mugen one, I'm sure you have seen those.
