Perfect for me. But may not be for others.

Quality: great.
Sound: 1 being stock and 10 being straight pipe. This is a 3/10. (Which is perfect for me). It’s just slightly louder but has a deeper growl. Keep in mind I do not have an upgraded down pipe.
No crackle pops but some gurgles are present now.
Install: easy pezzy. Done with jack stands. Used dish soap for hangers and came off with ease. Pieces aligned perfectly.
Power gains: not very noticeable. I think it sheds about 15
10lbs from stock.
Drone: I have not noticed it yet and non of my passengers have mentioned anything on the city or highway.
The finish on the tips look very shiny at first but once installed it looks like the stock finish.
If noise was 5/10 from the scale I mentioned above I would give it 5stars. But then it would no longer be perfect for me.
Besides catback exhaust I only have prl cobra cai. (5/5 stars)
