Pics of the Prospeed Headers you guys been waiting for!
Here are some pics you guys have been waiting for. We have them for H22a's, B-series, D-series, and coming soon the K-series headers! Dyno graphs are coming soon The H22a headers fit on 92-00 civics,94-01 integras and 94+ Accords.

on his website it says about 750 for SS w/ merge collectors. thats for the b series... i hope the pricing is the same! the h series headers are availible now?
Hi Guys i will try to answer all your questions. The price is $500 for the street collector and for the merge collector it will be $700. They are stepped and are equal length. The primaries are stepped from 1 3/4 to 1 7/8. The collector is 2 1/2 inch. The Ground clearance is not that bad i will have pics of it in a civic and dyno figures up very soon for you guys! It will be a comparison from the DC headers. We will have the headers up on our site already. I will put more info on there when i get a chance. The headers fit H22as in Civics 92-00 and Accords with H22a's. It will also clear the A/C. More info will be up soon! Thanks

We offer both drag headers and street headers. The pics above are the street headers. Right now there isn't enough demand for the f22a. If enough people are interested in a header for the F22a we might start offering it.
are your primaries exact equal length or just really close? some people interpet "equal length" as different things
I am curious as to why your design utilizes so many bends? witht eh room on the front end of an Accord seems you could get maximum performance out of a design that has a smoother flow from the head to the collector, keeping the gas hotter in return moving faster, smoother, and collecting smoother
I ask purely from an R&D perspective, you build them so you would know better than me

thanks prospeed for this initial information. we are all looking forward to the dyno tests im sure. but i can say as of now this may be my top choice for an NA header. the price, and qulity is just right... gimme a couple months though, i need a truck and trailor first
hurry up foooo . jes playing. i want to see da results my self. are you doing dyno testing againts other headers to?
oh yea can u take pictures i wanna checks them out in da car see how pimp they look.

LOL Right now we are doing it only against the DC Sports header. Seems like everyone and their mom has a DC sports header! I will test it against other headers later down the road.
I have had these headers in my car for a few weeks now. They're pretty awesome, unlike any other bolt on I've put on before. Gonna go dyno next week sometime. Sorry i dont have a baseline, but the nimbers alone should be enough, to speak for themselves. I have all the basic mods everyone else has, + the Jun valvetrain kit and cams. just ask Prospeed for them, thats where i got mine. I'll post as soon as I have some dyno #'s.
