You can take a bunch of diffuser disks off the Supertrapp and it'll be a little quieter.
I happen to love annoying my Harley driving neighbors with the loudness (I have 8 disks in mine). Since its just a pipe (I don't think there's a flange ... I'll have to look) pretty much any muffler will work ... or at least can be made to work. |

Yep, just had to run out to the parking lot to throw the roof on (rain a comin') and looked under the car, there is a flange.
well if you didn't mind destroying the Supertrapp, you could cut the flange off it and weld it to any other muffler. |

Autozone sells hush thrush mufflers. Its an oval muffler.
Its very open, but tones down the 914 nicely. They dont sell flanges, but a decent muffler shop will sell you a flange, or they will even tig one on your muffler for you. I had an original (pre Foley) header like foley makes. I got the muffler and flange...welded it up and added a bolt on tail pipe to pass tech/noise inspection..simple. Rich |

What are you running behind the header? I have a super trapp and it is just to loud. what are my options? I recommend a long pipe (about 36" long) from the flange that makes a turn behind the tranny to a conventional chambered muffler, and a tailpipe on the other end. |

Chris Should the 36" pipe be the same size as the collector? my other option is to install that 1st generation setup I have that you made.. how quiet is this setup? Attached image(s) |

If you have that, what are you messing around with the KHH for?
More power, quieter, nicer sound, heat, looks cool, new, more power. Just the Stage I is as loud as the Supertrapp with no plates. Adding the second stage silencer makes it quite reasonable for the street. The KHH extension pipe should be 2 1/8" or 2 1/4". BTW, I can help you update the Tangerine heat exchanger to distribute air to both sides of the cockpit. |
