Anyone have really bad hissing noises coming from Berk Testpipes for a g37x coupe if so how can you fix it lol

 

The Berk HFCs are like that too

 

only way to get rid of the noise would be to replace them with different ones right?

 

is it hissing when you let out the throttle and the rpms are coming down? If so that is just the "vq hiss". I don't have berk tp but i do have the hiss. Now if its hissing when you are on the throttle then I'm not sure about a fix. I've heard lots of clip with different free flowing setups that all hissed at the bottom end of the rpm range when letting out the throttle.
