Smell is not bad, was expecting much worse. What im not a big fan of is a rattling sound that seems to be comong from the back/exhaust...sounds like a common problem after going catless

Here's a small sample of what it sounds like from the driver's point of view with a Stage 2 BPM tune and stock M-Sport exhaust. I stepped on it at around 40 mph when merging onto the highway (when you see the traction control flash for a moment.) Had to slow down due to traffic in front of me.
