Not to mention the sound can also be variable depending on how you modulate the throttle.

What's also great about the Dinan piece, is that its very close to OE fit, and it's reverse compatible.

If after that mod, you don't find it loud enough you can add a muffler.
This is what I'm leaning towards since both resonators are going to be replaced with this anyways
