Reviving an old thread here looking for some input. I really like the Kreissieg sound, but there is no way I would even consider paying that much. RPi's have a similar sound, but the videos make it seem like it doesn't have quite the exotic tone at high rpms like the Kreissieg does.
My question is, what would be the best way to achieve this sound with the RPi exhaust? Would the RE X-Pipe be best? Or Euro headers? Any input is appreciated...
