vibration from silenced decat

[Anonymous]

Got my Williams back from GDi yesterday after I swapped the engine from my Hybrid.
Andy did a top job and the car sailed through its MOT.

However when the car reaches 3k rpm there is a nasty vibration sound coming from the silenced decat and I believe the baffles are shot and causing the noise.
I have got 2 straight through unsilenced decats in the garage but they are for 16v's

My questions is this, can I remove my silenced decat and smash/remove the baffles that are vibrating so it becomes unsilenced?

yes but why bother mate - throw it in the bin and fit a straight through one!

Both my straight through's are for the valver mate and the flanges dont mate up.

I'm just looking for a quick fix as I will buy one saturday, just wanna see if this will work.

Whats the best way to break the baffles? Just a long meaty screwdriver jabbed into the decat?
