Feedback from those with SLP Loudmouth II already installed?

Waiting on a 2SS/RS to come in....will definitely be upgrading to get more SS V8 rumble out of the exhaust. On that point, Loudmouth II from SLP is the best sounding system I've heard (based on available video clips). Would appreciate any comments from those who have already had it installed on their SS. Specifically, any concerns that it might be too loud for daily driving(so as to attract unwanted cop/ticket attention due to overly loud exhaust)? I don't believe that will be the case on LM II , but would appreciate insight from those who have actually had it installed. Also, any comments as to how LM II sounds from inside the car would be great also. Thank you...

You can only pre order the SLP stuff. So I'm sure no one has it yet. But I want SLP too!!

Bump...anyone installed this yet? Specifically, is there any crackle/gurgle in the exhaust when decelerating?

I get terrible gurgle with my straight pipes, and am looking for a solution. I love the LM2 on my 02 Z28 but want to get rid of the gurgle.

I ordered and it was shipped today according to my email tracker. My guess is the exhaust will get here before the car. I will post video once received with my thoughts on it. I agree awesome sound.
