What is the concensus out there on the GLM manifolds and risers compared to the OE Volvo?
Thanks

Consensus is:

They cost less.

Oh yeah, they still hold up as well.

Been running Aluminum GLM's I bought directly from Dennis Moore for 2 seasons on a Merc SBC....picked up a few RPM's (better internal runner design), perfect fit and finish.
Look great w/ Merc HP Blue paint.
