Wow. Sounds really good in the sound clip. Wish I could hear it in person. So, how much rasp is there? I can hear a little in the sound clip, but that's almost impossible to avoid when reving the throttle like that. Also, do you get any drone on the highway or at certain speeds at all?

Oh yes, and BTW, sounds great.

There is a little rasp but it's minimal. There is also a little drone when you're around 2800 rpms but it was like that with the stock cats as well. If you're above or below it's surprisingly quiet.

Very cool. Sounds like it would be very similar to my set-up with the Berk HFC's. I might have to give these a shot when / if I ever get my car back from GTM. LOL
