Vrsf 3.5in exhuast Leak

Recently bought vrsf's 3.5 in cat back exhaust and i really like it, not to loud but still sounds great.
However, no matter what I do, the exhaust leaks from all 3 connections that use the large exhaust clamps.
The only leak that is actually noticeable is section 1 to section 2. I have loosened and re tightened this connection at least 5 times and it still leaks.
Has anyone else had this issue or am I just special?

If i could I would be happy to buy a new clamp for that one spot.

I have this exhaust & you need to make sure that all the tubes are fully pressed into the band clamps. Have someone hold the tube pressed into place while you tightened the clamps pretty tight

Also make sure the clamps are installed in the correct orientation. If they're installed backwards they will not seal well. One side is larger than the other
