there is a such thing as a exhaust donut, it is the gasket that fits where the exhaust manifold and exhaust piping meets.

it can cause a lack of power by messing with the o2 sensors from an exhaust leak.

its either that, or an exhaust leak.

maybe even a plugged catalytic convertor which could be causing the noise and power loss.
