Header Question!

[mari_ambition]

Well sadly my manifold has rotted out and has holes and I decided to get a header but I dont want a $800 header and figure out I could have use that somewhere else to increase my HP..so I went the cheap way and got a deal for $50 and I dont know if it will fit my CB7...HELP

Try installing it...really only way you can see if it fits.

If you bought it for a '90-'93 Accord (which it looks like) then I don't really understand your question. Why wouldn't it work. I would replace the gaskets on it with better quality ones. Search around and you'll find others that have detailed the steps necessary with this header.

Looks to be a fairly decent piece - even looks as if someone went to the effort to clean up the welds on the interior where the pipe meets the flange. I'd say give it a try as well - getting better gaskets as suggested previously is an excellent idea - though you might try the fit first.

I went to go get it installed guy was like ohh im late for a meeting ...then he said "Civic and accords looks similar, I dont know what one this is".."it will be $150"..so im my head im thinking this guy is suspect..and I got this randomly..like last night at midnight..i was thinking about wrapping header but people always tell me not too..

That usually isn't required if you were using a good welder with experience. There should be no requirement for extensive grinding on the back side of a TIG/MIG weld if it was done properly.

But for $50 what do you expect.... Looks like a simple 4-2-1 design based off the OEM tube manifold. Might as well give it a try and see what happens!

In retrospect I agree with your comment whole heatedly. Now it makes me wonder if the tubing hadn't been chopped sawed, bent, & then welded to the flange. Perhaps the grinding on the interior was more of a deburring process, & as you suggest - weld should not have made it to that side.

I will say from a welder/fabricators perspective if it's a good weld it will hold and u won't need to grind it down, if it's been ground down the it was a bad weld and if they don't know what the hell there doing then their most likley just grinding off to much making the weld weaker then it already was

I have the exact same header on my car at the moment, only difference is that I am using my oem replacement a4 down pipe resulting in a poor angle and the downpipe hitting the front cross member causing a tiny bit of vibrations under load nothing that scares me though haha.

Those cheap things are only good as a replacement for a rotted stock manifold. You won't gain much power, and it may leak. It'll likely fail in a year or two tops... but for $50, it's not bad.

However, your thought of not spending money on a good header so you could get power elsewhere is flawed. The engine is a giant air pump. The greatest bottleneck will be what prevents you from making power. A poorly designed generic header will eventually be that bottleneck.
