Well, good news! No...great news! The system was only insanely loud inside my garage. Once I took it outside, it was perfect (for me). What a great exhaust note! And, on the highway, the drone is completely gone. Yea! Of course, when you gas it, it gets louder as it should. But, just cruising down the interstate at 75, it's really nice. You can hear the exhaust but it's not annoying like it was before. Since I installed Torq Loopz and TBR's as a system, I can't prove which one eliminated the drone but my money is on the Loopz. Anyway, I just couldn't be happier with my new exhaust .
