im thinking about getting a hytech replica header ... does anyone have any ideas of what these headers are making for power compared to other companies such as rmf .. smsp.. .and so forthe .. thank you .. opinions will help

 

They have been pretty comparable to the real thing at a fraction of the cost. I can't link to another forum for the dyno results, but they do very well with increasing hp..

 

bump for wanting to kno what he ader i should buy

 

dont buy a replica, not for an itr. i always say go big or go home. spend alot, its just money.

When my car was in B motor trim, I had extraordinarily good luck with an SMSP header and an SMSP 2.5" exhaust. Made remarkable improvements with relatively few other changes to the B motor.

However, for the $350 that you are probably going to pay for the Hytech replica, it is undoubtedly very hard to beat, assuming it is really a true Hytech replica. Jon at Hytech has always made a big deal over the fact that he has patented his anti-reversion collector and I do not understand how anybody could get away with copying a Hytech B motor header exactly, for only $350, if he is paying a licensing fee to Hytech.

There is an advertiser in the sponsor forums (Performance section) selling these for $350 and he even mentions that it is a Hytech replica.

I have no idea how he gets away with replicating patented devices, and no idea why John lets him get away with mentioning Hytech in the ad.

Nevertheless, if it <u>is</u> an <u>exact</u> Hytech replica, the $350 is an extraordinary and unbeatable deal.

You can buy cheaper versions of the SMSP header in mild steel, but I am not sure he's ever gone as low as $350 for all the work that goes into it.

 

what kind of #'s are the replicas making? I knew these were in production, but what kind of gains are people seeing?

The guy selling them in Performance parts here has some dynos available.

They seem to do about the same thing that a genuine Hytech or SMSP would be doing, namely, you'd be able to expect to get Dynojet 190 HP with relatively few other changes.

But...I'm telling you, when John finds out about this their whole sales strategy is going to come crashing down!!

EDIT: As with any high performance header, people should be aware of, check on and/or be prepared to deal with: https://honda-tech.com/zerothread/2345368

 

the header you speak of doesn't have the anit-reversion chambers .. so it isn't a replica exactly


The replica means the long SMSP/Hytech length 4-2-1 headers that take the place of your cat.

Do a search, i posted one a while back ... They make great mid-range and top end.. They will make a little less whp then a Toda but for 1/3 the price.

 

works for me then ... heres a picture of the one i just bought ... .

 

I won't lie... that is a nice looking piece for $350. And if its making close the Toda, then

 

Definitely a familiar looking header!

 

h1 racer Kevin Helms and his shop helper Corey have dyno'd these headers... they make different ones for b18 and b20 (FYI).

I know HondaWorks doesn't post a lot here but i have talked with everyone at the shop and said for just doing the HPDE and stuff that this header is the best bang for the buck.

5 whp less then TODA on a b20 vtec
3 ftq less

FYI
Sucks for for comanies like Hytech and SMSP but these are made in Cuba/other countries and the cost is 1/5 the price of there stuff. You can afford to hit/dent these and not feel it in your wallet.

Exactly.... not to mention its not far off what you'd pay for a stock JDM 4-1 piece that is making more power. George, you and i wonder the same thing though....and that is how in the world does John ever let this slide. They call the damn thing a "HyTech replica".

I believe Hytech has a patent on the anti-reversion chamber collector only, and not the way the header is shaped. That said, the Hytech replica headers do not have anti-reversion chambers on them, they just follow the same lines/curves that the real Hytech does.

and as everyone else mentioned, for $350, the Hytech replica header is a good bang for the buck. I have seen them in person, and they seem to be of pretty good quality.. Just my 2 cents.. I don't own one though.

 

guys i paid 300 for this off ebay.. come on thats an incredible deal .. i actually have another one for sale for 300 if anyone wants it

 

i thought about getting one but i just dont frrl right pitting a fake part om my R i mean my R's not a fake so why put fake parts on her but on the other hand...... i have dented my jdm itr heeders so..... im thinking about it and if it makes almost as much power as a toda!!! for far less the price im almost sold on it

 

i had both sitting in my room 6 months ago

The hytech is bigger in everyway. The tubes were noticable bigger and the length was a little bit longer. The welds speak for itself.

I also noticed that the replica was a little lower to the ground

Problems with the replica: Flange was welded on at an angle. It looked like it moved while they were welding it so it wasnt perfectly aligned. The welds were "OK" for the price. Alot of other replicas I've seen cracked on the flange.

You get what you pay for, luckily I held off on installing the replica and found a Hytech Anti-Reversion chamber header for $550 and sold the replica to a friend

Just MY 2 cents

 

friend made a 190 whp gsr block itr pistons with sk2 pro1 and that replica header. fyi he smashes the **** out of it cuz it hangs low better to smash the header then the oil pan right

 

I just bought one

What I would like to do is a comparo with a real Hytech or SMSP. Money is tight with my build so this will have to do for now. I'd like to get the real deal next year.

 

Very good bang for the buck. Just got one of these off the dyno for a customer.. Specs are as follows:

1994 Integra bone stock GSR motor with stock gsr cams 170K miles
Blox intake mani
AEM v1 CAI
Hytech Replica Header
2.5" test pipe
DC sports 2 3/8" catback exhaust
80 deg temps inside.
Car made 179 whp

I'll try and get the dyno sheet and post them up

agreed..

 

I had that header and it leaked...and I really hate that. also it sits pretty low and because of that two things I wouldnt buy another

 

a friend owned one of these and it had a very annoying rattle because one of the primaries was either not welded exactly straight or it was bent slightly to the point where it was slightly touching another...rattled like crazy.

read it and weep. my boy is 89civicdx. his hytech rep had 1.5" gc at best. if i owned an itr, i would not purchase that crap. i was one of the lucky people that bought this (hytech rep.)a few years ago when it was $199 on ebay. and i sold it soon after. the flange alignment is off on probably 5/10 headers made and they are prone to cracks and leaks. users beware. it makes power, but, so do other units
