I have the race Termignoni with a new map to upload to the bike.
1. Standard exhaust with standard map - not up to the standard of the GSXRs I've ridden for years.
2. Termi on, still with dB killer in and standard map. Big improvement in sound and fueling.
3. Termi on, dB killer out, standard map. The noise is from Satan's bowls>
, fueling a little less good than 2.
Waiting for it to get 1st service when new map will be uploaded to bike
