Default Roush High Performace Cat-Bak vs Loudmouth II's on a 2010 GT

Asking for opinions once again. I have SLP Loudmouth II's on my 2010 GT currently. I am wanting to go with the Roush High Performance Cat-Back Exhaust. I don't know anyone in the area who has a this Roush exhaust so the closest I have heard it is through videos and audio online and we all know it's nothing like hearing it in person. What am I getting myself into? How would you compare the Loudmouth II's to the Roush as far as sound quality? Thanks.

i've heard the LM2's and really don't like them too much(not aggressive enough for me) the Roush system is really nice, i'd pull the trigger on the Roush(but that's just me)

roush only has one exhaust for the 2010, its the extreme no matter what they are calling it. it sounds awesome, loud, aggressive, your neighbors may hate you. it has drone in some ranges, mostly around 2500 to 3000 from what i hear. Did i mention its loud? I drove a 427r that had it, and its one of the more popular systems on the boards. It sounds great, haven't heard the other one to compare. Vids simply don;t do the roush system justice.

I have said it before and I'll say it again: I have the Roush O/R (the only Roush exhaust for the 2010), and it's OUTSTANDING. I get compliments everywhere I go. If you stay out of the gas in your neighborhood, the neighbors will be fine.

As for drone, I got virtually none with my tune/gearing. But, as discussed a billion other times, drone is a crapshoot and varies by car.

I have the roush exhaust for sale if your interested. Ill make you a deal shipping wont be too bad since its only NC. I love it and the only reason I am selling it is because I did longtubes and its just too loud with the high flow cats and all. Let me know

all those catbacks you listed are very similar: midmounted, straight thru bullet style race mufflers, they will sound very similar.
so i think switching from a LM2 (which must be a custom job) to the roush wont be that much different, althought the roush system may be the best made system for fitment and materials.

There is nothing similar in sound to the roush. Its all about placement of the resonators. Roush hit the nail on the head. It is really amazing sounding in person.
