04 GTP blowing smoke out of the lower /rear exhaust manifold so I'm trying to replace the gasket. There are 100s of videos on intake manifold replacement but I can't find a single one regarding the exhaust manifold replacement. I know it's sandwiched between the engine and firewall and I had a hard enough time before just accessing the flange to attach a new downpipe a few years back, and the manifold looks almost inaccessible from any angle. If anyone has seen a good video or tutorial please let me know before I die from CO poisoning.
