I expect the audio doesn't do it justice, but if she's happy then great.

I just got a nice idea for exhaust which I'll share while it's on my mind. An X crossover which terminates on both sides of the mufflers, with a cut off valve in the middle.

With valve closed, quiet and a marginally power loss.

Open the valve, and power boost plus LOUD AS HELL.

Best applied when passing the bloke who has been going five miles under the speed limit, and speeds up at the passing lane.
