Time for new exhaust on the old 351. I see price differences in the hundreds between cast iron maniolds and wonder if there are significant quality differences.
Thanks

You can find some that are PCM replacements, some that are Indmar replacements, others for OMC/Volvo and some others too.

If you want the same fit to the exhaust hoses, getting PCM replacements would be your best bet if you have a PCM engine.

That's assuming that you're getting manifolds and risers.

If getting manifolds only, then PCM replacements would be your only bet so that the old risers would match up.

Not knowing what brands you're looking at, pretty much any of them are gonna last a long time in fresh water

Speaking of exhaust hoses, it would be a good idea to replace them at the same time, so that they don't start to leak like the fountain at the Bellagio..............or your speedometers Wink
