I picked up this muffler at Fast Times at Farmington over the weekend. The old dude said he took it off a 71 to put on a performance muffler... but now I'm thinking that tailpipe is wrong for a 71?
It's heavy, has indentions... and the damper pipe at least has a sticker that reads Made in West Germany on it. Does anyone recognize this? I'm interested in knowing the maker/country of origin, and if it will work on my stock 1600 DP?

That looks correct for 68-71 per the exhaust system diagram in the Bentley service manual. _________________ Don

That's a splitty tail pipe, but the rest is the same as 1600 bay, there were a few sellers (still some today) who had the tail pipe styles backwards. Bay pipes are straight with no downward bend.
The brand doesn't look familiar, but it looks like a fairly solid unit, try it out. _________________ Rust NEVER sleeps and stock never goes out of style.

I kind of thought this muffler would physically fit my bus... but I was worried that there would be some horsepower issue if it were the muffler for a splitty or something.
I only paid $30 bucks for it.. with no shipping... so no worries there... I just didn't want to do the work on installing it only to find our it was for a lower horse power motor. But I'm gathering that there is no problem in using it..
Thank you everyone! As usual!
I have a NOS VW tailpipe for a 71 on the way... No more embarrassing double pea shooters sticking out in back and trying to gas me to death! _________________ White 71 Campmobile known lovingly as "the Sulphur-Crested Cockatoo." |

The 40 horse muffler is narrower between the flanges (ports), measure the width of what's on there now, the difference is something like 3/4" _________________ Rust NEVER sleeps and stock never goes out of style.

Just measured up under my bus and it appears to be around 61 cm on center on the two ports closest to the pavement... Are these the ones you were talking about Busdaddy?
The muffler in question looks to be around 62 cm on center.. so that's either my error on the measurement up under the bus (most likely) or this muffler is wider than my motor if anything... which I'm taking to mean it will fit if I hit it with my 25 pound blacksmithing sledge hammer... _________________ White 71 Campmobile known lovingly as "the Sulphur-Crested Cockatoo." |

Sounds close enough, the whole engine is narrower on the 1200, by a noticeable margin. 27 5/8" is the center to center on a stock stroke 1600's #2 and #4 ports, now and then they warp a little from time and heat so a well placed whack may be what it needs. _________________ Rust NEVER sleeps and stock never goes out of style.

I have no doubt you could work some precise blows, but the vibration may cause internal issues on a muffler that old. I'd prefer heat and carefully applied force, myself. I've used heat and an insulated ratchet strap with good results, for shrinkage around 1/4" or so.

Just joking about the 25 pound hammer Robbie... although I do have one... and I am tempted sometimes! _________________ White 71 Campmobile known lovingly as "the Sulphur-Crested Cockatoo." |
