Friggin awesome to hear...I bought the Berk Testies...and I thought I'd get used to the rasp, perhaps I was in denial, but I swear the rasp echo is so bad in my car I sound like a stupid honda with ebay exhaust....its mainly in the 2.5-4k rpm range. I'll be wrapping...twice...three times.......anything to get rid of the noise.

The smell btw isn't too bad....just sucks when I back up into my garage...
