cp-e vs AA exhaust system

I had the AA first generation system in my e46 and I really like it, plus the guys from AA are very customer oriented, but, I just don't want to cut my exhaust.
I like the sound and the looks of the cp-e exhaust system and the bolt on is a plus.
What you guys think?

I thought AA was bolt on also? I've heard the AA exhaust, and have CP-E. I like the CP-E better.

When I was shopping for an exhaust system I followed the development of the cp-e exhaust however I just couldn't get myself to like the sound. I ultimately ended up with the AA system and am 100% satisfied with every aspect of it, as far as service goes you won't find anyone better then AA. I also posted a video of my exhaust a few days ago if you wanna hear it.

I'm happy with the way my CP-E sounds... its really deep and throaty with a mean sound to it. I've only heard clips of the AA exhaust, but I wasn't too thrilled with the sound.

huh these are the two exhausts that i am in between and do not know which one to do. I used to have a stillen exhaust on my g35 coupe and i absolutely loved the deep sound. I am leaning towards the cp-e b/c i feel like the AA exhaust is too loud at idle and would drive me banana's.

Is the cp-e loud at idle or only when you open it up?

You have to cut like six inches before the coupler. It's so dumb they did that, probably lost tons of customers.

I got the AA, and it sounds liks stock at idle, very quiet.
It sounds great too, only downside is drone at 2K, overall I like it.
