I got a single shot I personally bought new and only had about 6 months worth of use and always stored inside. I bought it and used it for 3 months and lost a part of the system then it wasn't used for like 7 years then I bought a 2nd system to get the missing part and I used it for about 3 more months then put a dual 2 1/2" on the car!
This system has all the ATR clamps and put bull muffler.
Just sold a dual 3" about 2 weeks ago it had the right mufflers too!
Just giving you another option in case you don't find what your looking for.
I can text pics of this system I snapped pics yesterday. Just text # below
