Thread: Interest in 4-1 stepped custom headers

I have been having more and more people ask about the custom stainless stepped 4-1 megaphone headers. I would never consider doing a group buy on these because you would need a lot of people to get the price down on materials. I would do a "mini" group buy on these headers if i can get maybe 5 people interested. I would only be able to drop the price because of me being able to build these all at once. All of these headers are built by hand and i DO NOT have jigs to build this header so they do take time.

Retail on this 4-1 header is $1749 with individual flanges and stainless V band.

I would be willing to bring the price down to the $1400-1500 range if i can get 5 people interested.

Just thought I would throw this out there.

Whats the difference between the gspec header and this when compared to each other.

This header is spec'd to the motor that you have. this is mainly for the built motor guys. This does make power on a healthy VE motor with all the good boltons but is best on a 2.2L or larger motor that is modified.

Which one of these headers make the best low to mid range torque?
Between 3800rpm-6200rpm.

this is the the best header all around period.

On a large cam DE the 4-1 stepped megaphone does, on a VE with N1 cams the 4-2-1 makes more power there but 6500+ the 4-1 pulls away.

I actually make a 4-2-1 similar to the budget header but a full stainless one. I make this in 2 different sizes, 1 5/8" - 1 3/4" and 1 3/4" - 1 7/8" primaries. These headers work great for mild built motors but great power from 4000-7000

chuck ive seen what youve done with 4 2 1's and im impressed.

but i have to ask you this, do you have any dyno sheets/proof that your 4:1's make the sort of gains that you claim ?

reason i ask is when i read your first post in this thread happynoles ve cam to mind that has your 4:1 headers, n1 cams, your n1 ported intake mani etc and it made 212 ?

im not trying to come off as a hater i just would like your opinion on why happynoles motor made some what sub par whp for the parts it had.

I have dyno'd the budget header vs the full custom header and when TUNED CORRECTLY it makes about 12whp gain over the budget @ 8000rpm. The 4-1 stepped ( the smaller choke one) makes more power than the budget header from 6900rpm+ and from 2000rpm- 4200rpm on average. The budget makes more power from 5000-7000rpm because that is what it is designed for.

On a larger 2.2L or larger motor that is modified the budget header will kill the build and you will need something better to get all the power out of it.

I do have the dyno sheets. I have tested numerous headers, even prototype headers that I still have and will not sell and I have not posted pics of. I actually have a full custom built 4-2-1 sitting at my shop right now, full stainless, SIMILAR to the budget header, but actually built with fully equal runners and perfect fitment. This header does cost a lot more ( more than 2x the budget) header but it will make more power than the budget header as well.

The budget header is just that. Awesome power on a budget. BUT i do have 4 other headers that on a VE motor with all the "typical" boltons with the ability to tune it, they will make more power than the Budget above 6500-7000rpm. Cost? $1000 MORE than the budget. which is why i dont build many of them.

hehe as much as i love my n/a i think i'd go turbo before spending that much on a header.. but im sure theres people out there with deep pockets..

i will just stick with the budget header when i get the cash, since im not doin a serious build anyway.

hope to see someone get one of these tho

Gotta pay to play.

On a $3000-$6000+ big-bore-build (2.2-2.4+) I do not think corners should be cut.

When the time is right & owners let me, I will post dyno sheets.

These headers make the power. End of story.
