Sound check with different exhausts on a Suzuki DR 650 SE (SP46) with Holeshot manifold.

### Headphones strongly recommended ###

I got my new LeoVince x3 together with a Holeshot manifold after the dull wool of my 12.000km MSR was fading due to a broken flame screen. Waiting for the new exhaust I was passing my time by binging tons of LeoVince videos on YT most of whom were poorly recorded with smart phones. This mostly destroys the whole sound by distorting the signal, compressing the sh*t out of it (which ruins the overall loudness impression and comparability) and messing up the frequency response. So time for some higher quality recordings of my currently available exhausts.

Exhausts used:
* Suzuki Stock (0:39)
* MSR stainless steel round (with and without silencer, 0:55 and 1:11)
* LeoVince x3 (with both silencers, 1:25 and 1:41)

Studio microphones:
* AKG C3000 (large diaphragm condenser for the lower end)
* AKG C1000 (small diaphragm condenser for the presence)

Preamp/Interface:
* Focusrite Scalett 2i2

Software:
* Debian Linux (O/S)
* Jack (soundserver)
* Audacity (wave editor)
* KDEnlive (video editing)

The recording was made at 48kHz/24bit. There was no clipping, the maximum peak was at ~-7dB. Both microphones are crossovered at 1kHz. There is nearly no post processing except a limiter for clearing out the highest spikes to enhance the audible range. This doesn't change the acoustic impression nor the loudness since the human brain already filters this kind of transients.

TL;DR: Clean recording, nearly no processing, the impression of loudness and sound correlates with the real experience.
