I just installed the SS Empi 4 into one exhaust and it's really nice. Quality workmanship etc. Sounds good too without being very loud _________________ 70 Ghia Black convert-9/69 build date-stock w/133k 1600 SP-barn find now with a rebuilt tranny and engine

If you don't want to go with the '72-74, 79 stock style muffler then buy a quality header (what you are calling a cross over pipe), a cheap one may not fit well from the get go and will be way more apt to fail in only 10-20K miles. This applies to cheap SS are well as just plain steel pipes and flanges, cheap thin stainless may not rust that fast but it may crack into pieces downright fast.
If you need to save money buy a cheap EMPI muffler to go with a top quality set of headers.
Note: The link to Kampers reposted below shows a stock style muffler for just $125. Not sure what shipping would be. Pretty hard to beat that price. If you aren't in salt country this muffle should last you 100K miles easily enough.

you can replace it with whatever style you want. That one is after market. The original VW Federal crossovers are NLA and even the used ones usually need repair before they can be used. _________________ “Most people don’t know what they’re doing, and a lot of them are really good at it.” - George Carlin |

If I need to replace the pipe, is that the one I need? http://www.jbugs.com/product/3319-7.html _________________ 1979 Type 2 w/ Weber 40 IDF carbs

These are what VW used for the 72-74 setups and look very 'correct' |

You have the easiest setup to need parts for already, good for you. That's a federal 79 btw.
You can go with the Vintage Speed stainless unit, the EMPI stainless unit or the regular EMPI unit easy.
http://www2.cip1.com/ProductDetails.asp?ProductCode=C13-3771
This is probably the one I would try next if mine was due. I have the Vintage Speed unit now and it's nice, but I think the engine does prefer a proper collector to some degree. The EMPI stainless won't last as long as the Vintage Speed unit im sure, because EMPI, but it'll last a hell of a lot longer than the standard EMPI unit.
Whatever you do - just don't get those god awful dual exhaust EMPI units and you'll be fine .. |

Definitely seem to have a driver's side heater box. The pipe (is it called the "crossover pipe?") that is attached to the driver's side heater box (and also the pas side heater box) is the pipe he claims is too rusty to use. You can see that the muffler on here is not a standard VW muffler and it looks like they had to weld the crossover pipe to it.

How do you know I have a 79 Cali system? Don't think I have a catalytic converter. The muffler guy showed me where the exhaust pipe bolts into the (heater box?) on the driver's side. This pipe needs to be replaced. I don't think I need to replace the heater boxes.
Fuel injection was ripped out before I bought the bus. I had Dellortos until they developed the dreaded Dellorto drip. Had them both repaired and rebuilt by Dave Hogarth of Blackline Racing but had to buy Webers in the interim. (Anyone interested in 44 IDF Dellortos?)
So, why am I looking for a 72-74 muffler exhaust pipe for a 79 bus? Just wondering? |
i guess we dont know what you have. the pictures in this thread are if the Cali system. post up some pictures then we can help better for you _________________ Rebuild your own FI Harness..My Harness

if you are in a non-smog state and plan on selling it in a non-smog state Mike's suggestion is the easiest solution. A double flange European style muffler can be used with this.
All this said - VW air cooled exhaust systems lasted about like other cars of their day - 40,000 to 60,000 miles. If you are younger than 50 years old you probably are accustomed to car exhausts that last near the life of the car because many of the components are stainless etc. Whatever you buy will not give you a trouble free existence unless you step up to a $1000 - $2000 stainless system without heater boxes. |

I have a factory stainless 72-74 exhaust on my 1800. Cost me all of $100 on eBay. Couldn't believe no one else bid against me. |

Look at the pictures SG Kent posted, you can see the difference in the driver's side side exhaust.
Once you have a driver's side '79 Federal heat exchanger to go with the passenger side heat exchanger you already have you can then run the much simpler, cheaper, and more available 72-74 style exhaust. |

Any negative ramifications blocking the EGR flow on a federal 2.0 FI?
Had a hole in pipe aft of view "g" small s pipe.....
Any word yet on Emico catalytics? |

HUH?
How do you replace the one part? The systems are completely different. On the CA system the exhaust goes thru the right exchanger, joins the exhaust directly from the left manifold, then goes thru the CAT, the ALL goes thru the left heat exchanger and to the muffler. Why?
I have no idea, but I bet it puts out a LOT more heat.
Further, if you have the CA system you have a oxy sensor and the wiring harness is quite a bit different as well. they do not have a resistance unit on the firewall and the double relay is different.

Well for starters he doesn't have FI any more so doesn't need the O2 sensor and would likely be better off without the cat as his signature says:
