Exhaust Valve flapping noise?

[Acexxon]

Hi I have the full Akra exhaust system and recently I have been hearing rattling noise which sound like something is rattling in the back of the exhaust system. I assume is the exhaust valve rattling? Anyone had experienced this?

I still have the OEM downpipes, so it's not the wastegate...

check all the brackets.... one could be loose. Also check the piping to make sure its not in contact with any of the body. AKRA is top notch quality so the pipes will be within spec, unless they were bent while install. Best thing to do is get the car on a life and start..... then zero in on the rattle.

It's the valve flap that's causing the noise... I don't know why, but it's kinda fixed now. Friend tightened one of the part for me for the flap and now it's much better.
