What company makes a header for the Preludes that have a 2.5" collector?

 

smsp, rmf

do a quick search. the dc isn't confirmed either (as far as i know, just rumors)

 

DC has a 2.5" collector header, but only for the SH

 

I thought the DC 2.5s were only for the 4th gen..at least thats what their site said the last time i looked.

 

I have the same question...I think that besides DC, there arent any headers you can buy unless its custom. Hopefully someone can prove me wrong.

 

Im trying to prove you wrong but unfortunately i dont think its going to happen, unless of course we go custom, which we def arent doing on a stock motor

so true. I heard that the vibrant header was 2.5inch but I contacted the main people and they said it was 2.25" oh well..I tried

 

Cool man thanks a lot for all your help, i guess this customer is hosed unless he wants to do a crazy build

 

He is not Hosed

Have the manifold Collector modified at and exhaust shop to 2.5 then run the appropriate pipes....less the customer doesnt want to see a weld on the header/exhaust...in that case he shouldnt get a header/manifold in the first place...under the car is not the place for showmanship

 

whats this about dc header for sh being 2.5", thats the first time i hear this

 

My SH DC Header bolted right up to the OEM components.....so I doubt its 2.5 collector

well OEM Cat...

 

If i welded a 2.5" collector onto the DC sports header right now that is only 2 1/4", it still wouldnt flow because of the runners, so it wouldnt make any sense to do that

 

explicit speed racing has one with a 2 1/2 inch collecter for $325
give them a call

Its not really that different from the 2.5" collector DC mods.

 

I do not know what is wrong with your DCs but mine has a 2.5" collector:

DC Sports does have a header with a 2.5" collector for the 93-96 H22. Part number HHC5029. I called on it today actually. The tech at DC Sports/AEM told me that it has the same primaries as the same header for the prelude with 2.25" collector.

Will this header, with the same size primaries as the 2.25" collector header, make much of a performance gain with 2.5" collector?

 

yes. there have been plenty of discussions about this do a better search.

The basic DC header has a 2" collector.

The primaries on the DC 4-2-1 are 1-5/8". That works well for a built up D series but not a stock H22.


T S R Performance, why not custom on a stock engine? Also go with a 2-1/2" cat, exhaust and tuning and you'll see very nice gains.

 

true that dave. Custom is the only way to go

 

Mugen is 2.5" collector also.

u sure about that?

 

I want to say that it's 60mm.


And custom headers work great on stock motors

 

Bump for some more info...Any good header that is not custom!?

 

Why buy a mass-produced header and feed the rich??

Buy custom and help out the guys who are making the worthwhile stuff for hondas!

Dave has the idea, custom headers work wonders on stock h22s.....my custom rmf combined with an electronic cutout is probably close to the biggest power gain you could get on an otherwise stock h22 for around $1000, and still be daily drivable....(no i don't want to hear your NOS ideas)

 

LOL! You are right but I think that 800 bucks is way too much money to spend on one single item! If I ever do get a header, I want it to be stainless steel. I like shiny stuff and stuff that will last long (ie. No rust). Does he have a header cheaper than 800? Thanks
