I had my exhuast installed yesterday as planned.
Love it. Not too loud not too quiet, just perfect for my taste
1. No drone on highway btw 100-120km ( havent had a chance to test other speed range yet )
2. Quiet while cruising, and roars at wot, and those bubble noise is just intoxicating; I am trying to find under what circumstances this exhaust makes this noise.
3. Dont feel any power gains. If there is, i dont notice it or hard to tell.
4. Sexy titanium tip is just a bonus. The tip stick out a bit, but i think invifia did this on purpose to show off the tip lol.
Overall happy with my choice.
