Type4 conversion exhaust

[Mile High Puma]

I have been plugging away at a type4 conversion for my 65 DC and have gotten to the part that I am expecting to be a real pain, the exhaust. I am sure there have been some splitty's with this done so maybe I can get some ideas. I have some 411 pipes and I am hoping that I can fit a stock 73-74 muffler without any apron modifications. Has anyone tried it and if it won't work were you able to install something that does not hang out the bottom or is much louder that stock?

very interesting how things have changed in the last 20 years or so. back in the day type 4 upright conversions involved porsche 911 fans and such. The german tuners offered type 4 exhausts that looked like beetle exhausts, etc.

like so:

i like this a lot, i am going to keep watching.

With stock 73, 74 heater boxes you can bolt a single exhaust muffler across the outlets and put on a turn out tube for a neat , installation.- will try and find my pics.

Zuggbug, the tranny I put together was from different year type 1 units with the stock big nut boxes. Used a 72 case with 73 "002" gearset which has the stronger mainshaft, splined coarse third and fourth gears from a bay bus trans., and 3.88 ring gear on a 70 Canadian bug swing diff. that my sister once had. This setup also gave me the later style throw out bearing setup.

This is what I used in the Mid 1990's on a 66 Standard Bus, same engine bay as your Double Cab Pretty Much. I shortened the 411 heater boxes after cutting off the sheet metal and used this. I added a locally sourced round muffler and it looked nice, sounded nice, and fit nice. It was really cheap and easy. The hardest job is cleaning out the flanges you cut off the original 411 tubes and sliding then down and welding flat.

Vintage Speed exhaust and headers specifically for a type 4 motor in a split bus. I went this route as the fabrication would have taken more time than I had.

It looks like the outlet hangs really low but it actually sits in exactly the same position as the stock exhaust. Also has O2 sensor ports which have been useful when tuning with a wideband.

I don't have a close up handy, but you can see a full bumper and a stock uncut apron in this image.

Did you buy a specific kit to do the type 4 conversion? Or did you fab as you go.

It looks like he is doing the classic Joe Cali conversion located here:

He sells a manual that will guide you to create your own upright conversion using mostly VW OEM sheet metal slightly modified. I did one in the past and it was very nice, but in the final hours I purchased the Fat Performance unit and a 911 fan setup. I will say this one here is as nice as i have seen. His work on the tins looks great and this will be a sweet double cab. I want to hear more about the Transmission, his picture gallery shows some views but not all of them.

Yes, I did buy the manual from Joe to use as a guide. A lot of the detail work you just have to make up your self like the tin, combination of type 1 and type 4 tin to get the engine compartment sealed up. I ended up making the gen/alt stand from steel stock as the one I purchased form Jake Raby for the DTM system would not let me set the fan housing back far enough to center it between the cylinders. Also the stand in Joe's book is aluminum which I did not have the proper welder to fabricate it. After all of the mods I did to the Scat shroud I think it would have been easier to modify a stock one by trimming off the heater ducts like the Sharp shrouds.

I just marked the headers where they touched the pushrod tubes, removed them and filed a bit away with one of these:

I just did a little at a time & kept refitting the header to test until I could get a feeler blade between the header and pushrod tube.
