GP exhaust resosance

Anyone else been in the back of a GP GT lately? My in-laws' 01 GP PT has a rather annoying exhaust resonance below 2k rpm.

I have a similar resonance now with my new exhaust. It's not that bad....just have to keep the revs above 2000. :twisted:

I have a loud, rumbling resonance that's quite a bit louder than the L36 GP, tone is similar, also at 2000rpm. Completely stock exhaust.

Methinks it's cause of the catalytic converter, the origins of which are completely unknown (it's not a standard issue Bonneville/H-body feline converter) - but it fits :?
