2022-01-22 - Exhaust Manifold Flange
Q:
Am I allowed to replace the flange on an exhaust manifold?
The stock flange design makes removal of the downpipe a bit challenging. I'd like to cut the flange off the manifold and replace it with a welded V-band flange.
This is "modifying the manifold" so I'm not sure this is allowed, but it is downstream of the merge
A:
You can change and use the clamping device of your choice on the end of the exhaust manifold..
