The sound is MUCH improved. This is actually rev 3 of the exhaust.
Rev 1 was just the Super 40
Rev 2 I added a 4" stainless packed bullet resonator
Rev 3 I replaced the bullet resonator with a 5" glasspack magnaflow muffler

NOW I have the sound I was looking for. Deep, aggressive, breathy. It is still very loud; we are talking about a Super 40 here with no cats. I wouldn't really call it a drone, but it is loud even at a cruise. I drove it 12 hours each way to the beach last year and it was too long, my ears were tired by the end.
