Check all the exhaust bolts.

Header bolts (2)
Header mount (1)
Header to Muffler clamp (1) (behind the rear brake reservoir)
Muffler mount (1)

Use Loctite and proper torque spec.

If this does not resolve the issue, check other bolts and clamps. also check the idle air screw setting.

There is a Tech Day in Cloverdale on August 9th.
