88-96, USDM & JDM: Aftermarket Headers/Extractors
Unfortunately like most items, there are no aftermarket headers/extractors directly available for the wagon. However, extractors designed to fit in a Civic Hatchback or CRX will fit into a 2WD Wagon without any problems, provided they are for the engine that you have.
However, for the 4WD Wagoneers the transfer case limits the ammount of space for the collector pipe, therefore making it near impossible to have 4-2-1 exctractors. The JDM Shuttle RTi comes standard with a SOHC ZC that has 4-2-1 exhust manifold and this will bolt up to SOHC D-series motors. It will also clear the transfer case on 4WD models, making it a good (but still OE) choice for SOHC 4WDers.
For 4WD models with a DOHC conversion you will need to have an
but the 2-1 collector is much shorter than the DOHC ZC 2-1 collector. 4WD DOHC ZC conversions can use the stock 2-1 collector (2nd piece) from a JDM Shuttle RTi (SOHC ZC) and the stock 4-2 manifold (1st piece) from the DOHC ZC for an OE style, otherwise you will need to get an existing aftermarket set modified to collect into one before going between the engine and transfer case.
If you want 4-1 extractors for your 4WD wagon you may need to have the collector modified the pass slightly lower under the transfer case.

actually dude, there is a header that will fit on our wagons.
i have it and there was no extra customizing necessary..it bolt right on.
DC Sports is the first name in headers for your Honda. The two-piece design allows for easier installation with its factory style O-rings and dual flanges. The DC Sports 4-2-1 header is designed for increased power throughout the RPM range and features lightweight CNC machined flanges, CNC mandrel bent tubes, and robotic TIG welded construction. The high-quality 1018 mild steel construction is ceramic coated for optimal heat insulation. CARB exempt and 50-state legal. All hardware and installation instructions included.

Its the 4WD that has clearance issues... 2WD shouldn't have any problems.
its not fun im a machinest and have made alot of funky stuff fit but this was a tuff one
I am gettin an aftermarket header off of honda-tech to see if I can have that one installed, do some pics & post em here.
I'm not sure if anyone in the US has actually done it to their wagon but i live in New Zealand and we basicly only get JDM cars here.. anyway to the point, i didn't purposely source the collector, i have a Shuttle RTi which comes with the SOHC ZC and 4-2-1 header, so i swapped in the DOHC ZC and used the 4-2 piece off the DOHC motor and the 2-1 collector from the SOHC motor and it fits together perfectly (which was lucky because i was about to have a header fabricated!).
As for sourcing one, i know that some JDM integra's came with the SOHC ZC as well so thats another car you could base your search on..
Just off the cuff, i called Strong Honda today and they have that piece available for $40 + GST NZD ($29.60 USD!!) + shipping, gimmie a PM or hit them up yourself at http://www.stronghonda.co.nz ... No idea what shipping will cost you but that sounds almost too cheap to pass up.
89 RT4wd
DC header # HHC5002 278.00 no tax/shipping from
importreplacementparts.com (good service)
Catco cat #? 51.95 with shipping Ebay.
Dynomax super turbo muffler # 17731N 120.00 installed with tip and pipe. The muffler usually costs around 40.00 by itself.
If you want a stock look you could try to locate a DST # 17778 which gives you the dual tips, but it's hard to find and costs more.
A SOHC ZC goes in this summer.
as far as exhaust, the ansewr is NO a hatchback exhaust will not be a direct bolt on. you would have to extend the main piping about a foot or so cause the wagon is longer also the tailpipe would have to be extended. not sure if the hook mounts are the same, but pretty sure there is some difference
its not that hard though to fab one up for it though
