Hey everybody. I have 2015 5.7 gxi with catalytic converters and alluminum manifolds and risers. I want to instal a full system for this season. I did a lots of research but couldn't find any useful information on wich system is suitable for this engine. Thanks in advance for any suggestions.

 

That's strange, no experience, noone?

 

The companies that sell these closed cooling systems to add-on don't list whether it will your fit your engine? There is some concern about adding closed cooling to an engine that has been running raw water cooling for several years.
