Exhaust whistle?

Hey guys i had a custom axleback installed past month, and i have a slight whistle or blow off valve sound at 3800-4500 and it annoys me alot and you can hear it on rev. I had 2 exhaust shops check welds and no leaks i do not know what to do =( the previous owner did not have this problem on his car. Thanks for the advice in advance!

Had the welding checked by two shops maybe i can try a third, one told me that they would cut it all apart and reweld if i wanted but. they said its fairly useless.

I would get the car up on a lift and rev it, and hold your hand near the different joints. You should be able to figure out where it is coming from.

Found the problem! seems like the clamps are either to loose, or not fitting right i may have to invest in new clamps.
