Exactly what I was looking for
I installed this yesterday and it did exactly what I was hoping it would do. I installed it on a modified 2010 Camaro SS right after the transmission with the hopes of it quitting it down just a couple notches. Still sounds great but cold starts are more mild (maybe my neighbors won't be as angry at me in the mornings lol) and eliminated some drone too. Shipped fast also! Thanks

Mellowed out my stock system
The stock system on my car was just a bit louder than I liked when the muffler valves were open. Replacing the stock midpipe's X + bullet resonators with a stamped X followed by this resonated X filtered out a bit more of the high frequency sound and reduced the overall volume, and at an excellent price. 9 months in and it doesn't seem to have lost any of its effectiveness.

Good quality
Got rid of the hillbilly straight piped sound of a 6.0 LS engine.
