anyone else seen the new Protech-Fabrication 4-1 header?
Was just curious if anyone else seen it and what you think about it? .. they said it was 23" and stepped aswell .. didnt really say much else about design and the owner hasnt posted results yet either.

yes I have seen it, that very one too

yes its stepped, and from my understanding numbers to compare are coming soon.

I think it looks expensive as hell.

I believe they said around 12-1500 when alls said and done but not entirely positive on the price .. it looks awesome in my opinion and of it performs well I may just have to snag one lol

Header is mine. Bruce at Protech made this v3 of his 4-1 headers and his idea was to keep the collector above the cross member to make the car streetable to lessen then chances of bottoming out. Originally i had called in to inquire about his 4-1 header. We talked for a long time and he expressed his intentions with a new design header and asked me if I was interested. I finally agreed to do it and he began working on it . The finished product is in the pictures in the OP. Specs are as follow:
1 3/4" to 1 7/8" stepped Equal length 23" runners, 2 1/4" choke reverse cone to 3" vband with splitter on 3" mid pipe with skid plate.

I just went high comp with n1 pistons and currently in tuning stages. Once my car is finished, I plan on taking it to the drag strip and doing work. After that I will be testing the header on a friends bolt on VE with ssac header and put it to the challenge.

Price on the header complete with skid plate, coating and mid pipe is $1350.00 plus shipping. Material is Mild Steel. It can also be made in Stainless Steel for more money but you would have to speak to Bruce.

armonic perf header. 1 3/4 primarys, 24inches long, 2 1/2 collector.

thanks for sharing the header dimensions Raul, reckon they will be really good. better than the one above.

Awesome work on these, but we need Dyno numbers. spending 1200-1500$ is crazy if your not building a crazy NA motor. I make my own tri-y and 4-1 headers, I'm positive mine won't support the same hp these do but I build mine for 350-400$. That means your paying 1000$ for 6-8hp. Now for the big NA builds wait for the proof/Dyno numbers because these manifolds look amazing.
