OE style exhaust

[Big Luni]

Any opinions/experiences w/ the German Motor Works OE-style exaust system for the '74?

[iltis74]

No experience (never seen one in person) but a couple thoughts I've had as I'm considering one too. You're going to have to remove at least the pipes to drop the motor. $200 is a buttload of money for a stock exaust, would probably be worth ceramic coating inside and out to protect your investment. It would be cool as hell poking out from the bumper, and chicks dig cool. Cost is what's holding me back because I would have to add coating and shipping and I already have an exhaust, but I still keep pulling up their page and peeking.

I have a German Motorworks/ Dansk exhaust on one of the 74 THINGs (THING 1) On THING 2, it has the original exhaust on it with the VW logo stamped onto the exhaust with the part number also stamped on the same location of the logo to it on the left.
The difference with the German Motorworks/ Dansk is the exhaust pipes do not bolt to the exhuast muffle, it slips over the fittings, the orginal exhuast pipes botl onto the muffler.

I have one of these.
Mine is not ceramic coated. Its year 2, and no rust or problems at all.
The unit fit on easily to a 100% stock U.S. Thing.
Did not effect the engine temp, and an readjustment of the stock 34PICT3 carb was not required.

You can get the unit with all new bolts, nuts, washers and gaskets and just connect it to your Thing - nothing else to buy and no special tools.
In fact, you can follow the instructions in the various repair manuals for a stock exhaust and everything is the same.

Compared to the exhaust systems I was able to put my hands on (2), the tubing and muffler metal seem a lot thicker - certainly more hefty than my original stock unit.

You can get a better performing exhaust, but it will require adjustments to your engine setup.

For a stock, bolt-on exhaust I think it is well worth the money and is hard to tell from the original unit.

I just purchased and installed the GMW exhaust when doing a complete engine rebuild. quality is good but I did have to rework the driver side preheating tin as it would not lineup with the hole in pan the hose goes through. my only disapointment is it is louder than I expected.

C.I.P. has the same muffler on sale now for less than $200.00 .I bought mine 3yrs ago & ceramic coated it, very happy with it.

Good tip Tyiii, I just placed an order, And with it, my car will be stock, other than the non-Mexican air on the tires

I just put on the CIP1 model for a '74 and it is horribly loud. Sounds like major exhaust leaks. If I hold towels over the tips it's quiet.
I hate driving it now. Other VW people look at me when I pull up somewhere and ask what's going on with my engine.

As others have said..."Buyer beware". I was warned and should have listened.



Has anyone had any luck making it quieter with a little surgery, like "germansupplyscott"?

The muffler I received had some Euro stickers on it, I think. Definitely not Empi stickers.
It also has the "air boxes" for the fresh air tubes to connect to.

The fit is fine, but the left side hangs lower (not parallel with bumper) due to sloppy craftsmanship. The right tail pipe also sticks out the bumper almost 1-1/2", while the left is flush.

Mine actually sounds better at full throttle. More like a header at that point, but at idle or light revs, it pops and sounds very hollow/tin can-ish (?). I tried fattening the mixture, but no luck. Played with timing as well.

Beetle pee shooters are larger diameter than the Cip1 tips as well, but holding them end to end sounds better.
I think I'll cut open a set, remove the outer chrome, and try to insert them.

I got mine from CIP1 with the stock tips. It was made in Denmark.

Fit was fine and sound is fine - a little louder than a stock Beetle exhaust but not much. I would expect it to be a little louder given the pipes have no baffling like pea shooters do.

I had to fiddle with the pipes to get them right - A little bending and bumper adjustment so they stick out about a half inch past the bumper on each side.

I played around a bit tonight.
Took off the outer bends and looked inside. Surprisingly, there are baffles inside. The 2/4 inlets actually block the outlets, preventing shoving a long perforated tube inside.

I cut up some pea shooters anyway to get the perforated tube out. Once removed from the outer chrome sleeve, I ground the outer flared end down to fit inside the muffler outlet tubing and cut it to about 6". It's only 1" ID, so there was no room for the packing - just the perforation.

I pounded it in a ways and then put the exhaust tip over the other end to finish seating it.

It's quieter, but not much. This, with pea shooters over the tips was very quiet.
I'm not read to clamp them on for the dual stinger look just yet, as a big engine and custom exhaust is in the near future.

I met this guy today who made a similar exhaust using pea shooters and curved conduit pipe. He says hes run it that way for a few years, at least 5,000 miles..he also had it coated

Basically,

1. plugged up the original peashooter holes
2. using a one inch hole saw, cut holes on the left and right ends
3. inserted peashooters into these ends (he said they are only in an inch or two)
4. welded them in. (I thin he reused the "flange"
5. attached curved conduit to the other end of the peashooter, welded it in
6. the plumbing conduit is bent at a curved 90, so it goes right through the bumper cutouts

It sounds great!

Does anyone who has the dansk repro know if you could just shove the peashooter tubes into the sides? Surxfx?

[sxuxrxf]

The pea shooters will NOT fit inside the existing tube. Not even close, which is why I cut them apart. You'd have to remove the stub tube and cut a larger hole. Also, the internals are in the way of shoving anything farther than an inch or so inside the muffler body.
Cip1 really should pull this POS from their website.

Of course they wont, everything I try to do that should be simple isnt...I was hoping that instead of modifying a beetle muffler, i could just stick the peashooters in the end and put on the conduit.

Grrr...however, the way the guy explained it, it wasnt that difficult to do the beetle muffler mods, pretty much cut, patch, weld

thats cool man! How does it sound?

I'm consistently amazed with how people outside the US "make do" and fabricate stuff (like janaurros stuff in mexico)

trying to get someone in the us to make a bend like that on an exhaust pipe in my area would be like "throwing a rock at the moon"
