How to further reduce noise???

[peterpeter]

Ive repacked my silencer, and its quieter now/
Only thing is, there is still alot of noise coming from the cut out hole where the 4 pipes emerge from the engine.
Is there any sound insulator available I can block the area around the pipes up- with???

Help much appreciated

Thanks.

I think it is from where the pipes come out from the block, so I guess I am looking at some gaskets.

Its a pinto, so any idea where I could get them from, and without sounding too ignorant, what do they look like???!!!
