Hello All,

I've got a 98 Firebird 5.0 TBI and I am replacing the Fuel Tank.
I will also be replacing the exhaust to make the job easier.
The new exhaust will be the FlowMaster 17233.

Does anyone know what bolts are used to bolt the Intermediate Exhaust
Pipe to the Catalytic Converter Flange ?

FlowMaster, Walker, GM, etc do not show any reference to the bolts.

Any suggestions will be appreciated.


Thanks,

 

Should be 10mm but mine broke and I drilled and tapped then to 3/8"
