Yes, we all know that with enough fweem you can beat Chuck Norris, and that with good fweem, women will want to be with you and men will want to be you. But what I want to know is what causes fweem? How could we reproduce fweem on other exhaust systems, or maybe other vehicles? (or would that be blasphemy?) Would modifying your exhaust tip to reproduce fweem on say a bigger displacement motor add to much back pressure? _________________ http://www.thesamba.com/vw/forum/viewtopic.php?t=366056 - My '73 Super Build. 2332cc, 16" Fuchs |

Fweem is all about the pea shooter tail pipes. The baffles in the tail pipes makes the fweem sound. I believe adjusting them in or out alters the sound as well. _________________ Joey

Typically, only the ones with loose baffles will fween.
The original factory tailpipes actually had fiberglass packing inside them. _________________ Society is like stew. If you don't keep it stirred up, you end up with a lot of scum on the top!--Edward Abbey

So it's the baffles? So if I were to get some like motor cycle baffles and put them up the pipe in my '99 S10 (with straight pipe) do you think it'd fweem? My theory is that it's the curve down to the small hole. _________________ http://www.thesamba.com/vw/forum/viewtopic.php?t=366056 - My '73 Super Build. 2332cc, 16" Fuchs |

I am driving a 1776 with 40 IDFs and straight pipe. I miss the fweem. High-po stuff is cool, but I am more of a stock guy  |

That fweet is instant childhood regression to me. My car echoing its fweet off the surrounding infrastructure with the window down is the best. I do notice that the smaller engines make a higher pitched sound. My 1500 does it a lot less than my fathers 1300 did. But there are still moments. _________________ What was done to me created me.

But I mean, if you put straight pipes on a 1300, it doesn't fweem anymore. So obviously it's a characteristic of the stock muffler. Hmm. Does anyone have good cutaway views of the muffler's guts and baffles? How bout the tips, those are a simple

It isn't the muffler, it is the tailpipes that do it, and only once they've broken in. We discussed this back, dunno, 13-4 years ago over on RAMVA, and IIRC, the consensus was the 'baffles' (screens?) that line the inside of the tailpipes make that fweem sound once the fiberglass packing starts to loosen up. _________________

I think you need to put a different pipe down. |

This is the inside of an original Type 3 muffler, circa 1964.

So the noise is a sort of whistling coming from all the holes perf'd into the various baffle things?
I wonder how fweemy a design like this would be? (top view obviously

Then a tip that was shaped like a beetle's except larger for a bigger motor. Obviously not to scale, or even proportion (those slashes would be more like louvers/baffles). And it wouldn't be to quiet, but would it fweem?  _________________ http://www.thesamba.com/vw/forum/viewtopic.php?t=366056 - My '73 Super Build. 2332cc, 16" Fuchs |

no, it's the pea shooters... take them out and replace them with anything, or nothing, and no fweem....my ghia has aftermarket tubes(flared), it doesn't fweem... new peashooters don't really fweem _________________
