Thread: Gasket replacement for Stock Manifold to 2.5" ZZP Downpipe

no need to undo the down pipe at all. just the manifold off the head. take the two dog bones off so you can push and or pull on the engine to move it as needed.

The engine has no mods except for HV3. The exhaust is all stock except for the downpipe, which is a ZZP stainless. On other threads, since this car is not highly modded that it is unlikely it is the exhaust manifold.
I have a walker stainless gasket 31605 ready to replace the one at the rear manifold and downpipe, but know you got me wondering if that may not be where the leak is due to all the noise, fumes and heat (exhaust gas is getting inside car) I have Seafoam and I can get it put into the upper intake and check for smoke.

the stock rear manny cracks stock, replacements also crack. or it could be the stock flex.
