Downpipe/Flexpipe Interchangability

[Chris_B]

Hello,
I am the owner of a 91 Accord Wagon, I know, not exactly a CB7 but close enough. My flex pipe has been leaking for the past year, its gotten pretty bad though so I figure its time to replace it. I called partsource and they said they can only get one for an LX model, I've got the EX-R.
I've read that the o2 sensor is on a different spot of the exhaust, the guy said the gaskets were different.
So my question is, can you use the downpipe interchangably between the DX, LX and EX models? and what about between coupes, sedans and wagons?
Also, what are the differences if you cant?

And, Honda wantws $268 for the flex pipe, partsource wanted $32, thought im sure gaskets are extra. But I was looking on Ebay for the downpipe and stumbled across incredibly cheap headers/downpipe. Item # 300230622238 for example. Just how shit are these? I don't really care about performance, my main concern with it would be longevity. I've read a bit on these forums and most people seem to bash them.. but it doesn't seem most people have tried them, so I'd prefer people with first hand experience. I've also read that you get alot of valve noise through the thiner metal, is that something you can definetly hear?

Thanks, Chris

A DX or LX has a 4-1 manifold meaning that the manifold goes straight from the 4 ports to 1 singe pipe and the o2 is on the mainfold.

On EX and SE the manifold is 4-2-1 meaning that the manifold goes from 4 ports to 2 ports down to 1 port. and the o2 is on the down pipe insterad of the manifold.

Your's is a EX-R wich in the states is considered a ex. So you will need the 4-2-1 diesign or just get a megan racing header. They are a good replacement part

Oh alright, perfect answer. The megan racing header is 190, i was hoping to spend a little less than that.. Does anybody know the quality of that ebay item I mentioned in my first post? And also, as for the coupe sedan wagon thing, will the exhaust all line up the same? Thanks

that should do it

Wow that one you posted is really cheap. I'd be worried about that.

I've bought headers w/ A-pipe off eBay before for the same reason. I can't find the seller I bought from, but it was essentially the same as the one you posted, except for $80 and it was ceramic. It also came with a "2 year warranty"...seeing as the seller isn't around anymore, it's not much of a warranty.

There is a little bit of rusting on the header pipes, as to be expected I suppose. It's been on since December and I haven't noticed any problems with the important stuff (welds and flex pipe) or any increased noise. Maybe I haven't noticed a difference in noise because my exhaust leak was so damn loud!

Anyways, if I had to, I'd go with the auction below.

Good luck!

Partsource you say?
Canadain i see.
Try and find something in the AUTO VALUE line. The 4-1 header downpipe was 90-ish, where the 4-2-1 downpipe was about 148 (this is my staff cost, so it may be a little more)

Part source is the wost place to go, they offer no warranty on that kind of stuff.

thanks for the replies guys, i like the look of the chrome one there.. does anybody know if it will fit a wagon for sure?

[ja23merz]

as long as you have an f22a motor, it should fit fine.

i wouldnt trust those cheap ebay headers the welds might be weak look into a meagan or DC header
