Weird Turbo Sound

[Sp3C14L 3D]

ok my turbo makes a weird chopping/fluttering sound when i get on it????? i just matched up a 3 cat delete race pipe to my stock exhaust, do you think its just caused by a change in back pressure??

bad DV? does it honk?

Sounds like an exhaust leak were the TP meets the exh.

im pretty sure its not the DV, but it very well could be an exhaust leak! hmmm thanks!
