Had my regular shop install three weeks ago. Sound very nice at mid range to high RPMs. When cruising the sound is not as sweet, kind of a low buzzy noise from 1600 to 2000 RPM. The overall tone is great and not too loud. May have the borla resonator replaced with a longer one to decrease the low buzz. The biggest issue was the install. The shop stated the existing hardware was very difficult to make work with the new system and had to get new stainless clamps to make it all work nicely.
