The exhaust has become loud ?? Fited a new Tyga exhaust system & sounded sweet for a few hundred kilometres around town & short trips. Did a 2 hr trip to Sydney & on the return trip the sound changed to rougher note. Removed the power valve & cleaned it all up, very dirty, but still the same. Fitted a new spark plug, not that would change anything. Sounds like an outboard boat motor now ! We swapped the Tyga muffler for another one the same & still the same note so it's not the muffler. Very strange, nothing was touched or changed, it just started making a different & more offensive & louder noise. Anyone else experienced this or have any idea why it is so. ?? And no change in performance, still goes like a scalded cat.
