I used a Sony Digital Recorder for my sounds files, but let's remember that none were done with the best accoustic surroundings. My pipes would most likely sound different on my recorder if I went to Robs house and made them, and vice versa. He recorded his in a garage, and mine were on a porch.
Sound wise, I like the Raask for it's sheer volume. Sounds like 1/2 of any Cobra type pipe on a v-twin....yep, loud.
I like the SuperTrapp, Mac, and Jardine for the mellower tones...in that order too.
However, in all fairness, my recording of a Jardine was done at a rally on a Savage that wasn't really tuned right and the Jardine had a loose baffle....so that file is merely an example, but not a perfect one.
Besides, comparing the Raask with the others is apples and oranges again....you can't compare a larger ID straight pipe with a stock header and a slip-on muffler. The total flow is different....
And let's not forget, we're all listening to these on different computer speakers and in different rooms, too. We just have no standard for either the recording or the playback.
But what the hay....we've got more sounds than any other forum. Thanks to Paladin for posting them
