Re: Catalytic Convert Replacement

What vibration are you talking about sound wave pulses, exhaust pulses, 
ridiculous. There is no way that doing this will cause something you can 
feel in engine vibration ,performance may be slightly, after 45 years of 
operating a shop, ASE master tech and former NHRA recorder holder with a
64 
Hemi super Stock car, I have experimented and run into all types of issues

like this and never experienced this " "vibration"!  Maybe your
terminology 
does not describe what you are focusing on?
