I bought mine from the company that sold me the conversion parts but any custom exhaust should be able to help you

i just make my own. i don't like how some of them are set up and run too close to the timing belt and or the thermostat/coolant hoses

If you have a 2.2L with dual port exhaust then KEP makes a decent (but pricey) header that also fits a 2.5L SOHC in case you want to upgrade later. I used one for my 2.5L swap into my 76 Westy and it worked out nicely. I also used a catalytic converter from a Vanagon and a Bug Pack muffler and it has good clearance from the plastic timing covers and coolant lines so I don't use a heat shield.

Have you looked at the OEM muffler setup on a Subaru BRZ? It’s pretty compact and fits right under the engine. A ton of Engineering goes into the factory exhaust system to create the perfect balance of power, efficiency, and sound Specific to the engine.

that is the catalytic converter, not the muffler.

Do you have a preferred supplier for the parts? I'm about there. My SC header just keeps cracking. |

FWIW.....I bought my primaries from Outfront then bought some mandrel piping in 90° and 180° then made my own up to the muffler of my choice. You can by flanges or buy some v-band clamps for better fitment. Maybe build off the factory heavy primaries? Is yours a dual exhaust port ?

| That box under the engine in my last post looked more like a primary muffler than a catalyst (it's pretty big for a cat), so I'm guessing the typical Suby to bus swap guy or gal would go without a cat. I personally like running catalytic converters, just to get rid of the stinky exhaust. The new cats are pretty efficient these days and take away virtually nothing from a performance perspective. I'd also think it would be pretty difficult to use the Subaru Power Control Module without an upstream and downstream O2 sensor input from the Catalyst (well that is if you don't mind the malfunction indicator light on all the time.....) |

Screen shot of the exhaust from my swap. Enough room for a trailer hitch and with the bumper on, you can't see the exhaust.

| Sweet looking setup! Looks like you got an aftermarket catalytic converter on there also. If you appreciate quiet, consider adding a resonator. I experimented with adding one to the cheap PaceSetter muffler on my type 4 air cooled motor and it made a significant reduction in noise. I bet you could find one from a Subaru Forester or similar that is tuned to attenuate the exact frequencies the Suby motor makes. Could also fit between your cat and muffler. Since I don’t actually have a Suby swapped bus, take my comments as suggestion only. I think Skills or Vdubnut may have real world experience to share |

i just buy a bunch of pipes from summit or jegs (same crap, just depends on what else i am ordering)
i try and build off the factory Y pipe. works well mostly unless the bus is slammed, then it's plan B

I used the Rocky Mountain Westy (now VanCafe) stainless header, and added my own muffler and hanger. Fits very well, isn't too loud (but louder thank stock), and has a very nice exhaust note.
Header:

Muffler:
Its a walker round body aluminized muffler. I'd have to dig up the PN
Upskirt pic:
From the back:
The passenger side bank primary pipe does run close to the water pump inlet connection, but there is plenty of room to work around it. I've had ZERO issues with any heat radiation from the header to the coolant pipes. Pic below from back when I was mocking it all up. I'm at 2.5 years and 10k miles on this arrangement now.
I've been extremely happy, and wouldn't change anything about the system.

Thanks 69BahamaYellow.
It's actually quieter than the aircooled was so I'm really happy with how it turned out. The Bugpack muffler is surprisingly quiet.

that's crazy. we tried that setup on davearks bus and i grabbed an extra 10* of heat.
for some reason, i think the one i used ran a bit closer to the t-stat. not shitting on it, if it works i'd call it a win

Yea, I remember you telling me that when I was originally building it. I already had all the stuff though, so I continued on with the RMW header. Obviously something in the two setups were different, since I've had no issues with mine.
Although it is close, I don't feel like its too close if you route the line carefully. I maximized the space around the rigid coolant line when I built it. I suppose some of the variations in the water pump and tstat housing could play into things too though.
