I am out of time since leaving on vacation tomorrow at 4am... and running since this week-end to get all done.... exhaust is pretty loud (louder than capristo) but brillant sound...no equivalent on the market for sure....

When cruising valve closed 3000rpm no issues its confortable. when valver open and goign into rpms..... wowww you feel this is race car hyou are drving almost..... love it... easy to install 2 hours 30 minutes and we remioved the capristo and placed the HMS.
