I have a 2002 340 Sundancer. It has 8.1s. I want to replace the manifolds, risers and elbows. They have seen 5 seasons now. I've been googling the parts and I noticed that besides OEM there are a few after market replacements. At least one claims to have a better warranty than Mercruiser OEM and also say their elbows/riser are stainless steel.
Are there better after market manifolds etc that are in fact better than the Mercruiser OEM parts (which are more money than the after market replacements)?

My 2000 380DA has the 454 MAG MPI Horizon engines, w/ the wet raw water exhaust.
Your 8.1 exhaust looks very cool.
On mine I was getting 3 to 4 years on the OEM parts prior to having to discard from corrosion. I redesigned the exhaust from impossible to drain / impossible to flush, to now drain / fresh water flush / soapy water flush / Salt Away flush / drain bone dry after each usage.
The exhaust was just disassembled for internal inspection after three years of usage. The internals of the parts look brand spanking new. At this point I would be justifying that the corrosion would still permit additional usage.
My boat has always had OEM parts. Others use aftermarket, probably based on part cost savings. The lower cost parts are probably fine.
