Shawn,

It's hard to say. I am on the inside and things are different.

I just got back from a little run. I only drove it home last night when we were done so now I had a chance to open it up on a nice twisty road punching it and shifting from second to third and back down (Decker Canyon Road for those familiar with Malibu) and it sounds great.

At idle just a subtle wuh wuh wuh, when feathering in traffic - still pretty quite, punch it and WOW! nice and deep with a rich healthy tone.

When I picked up my new sporty, it sounded like a Honda. I ask the Harley Dealer WTF? And they made me a deal on a set of Screaming Eagle mufflers. Then it sounded like a Harley. I removed the baffles in the SE mufflers and it sounded like Hells Angels. Put the baffles back in Happy with Harley Sound.

Same thing, I think it sounds like it should have stock. If you were to change the SRT Muffler you would remove the resonator anyway so look at it as a partial mod that won't go to waste.
