Tinny vibrations from ktec exhaust.

Hi guys. Does anyone else's ktec still give metallic/tinny vibrations? No matter how many times I've had it adjusted and realigned (sits perfect in centre of diffuser) it still gives a tinny vibration most of the time especially low revs. When you gun it you can't hear it at all :smiley:

I'm guessing it's one of the heat shields but I've no clue how to actually tell where it's coming from.can't afford to take it back to another garage abd the garage that fitted it had tbf been very patient with me and had looked at it on a number of occasions so I won't be taking it back. If there is something I could try myself I would.

Any help greatly appreciated

Cheers

Tim.
