First time responding on here so...
Catch Can story: purchased 2020 RST 6.2L on 5 Dec 2022 w/38k.
Immediately installed Corsa Catch and was amazed at how much was caught after each 3k check. During my drive from Sedona to Florida it occurred to me that this wasn't capturing from the valve covers like previous systems I've used.
After further research it was decided that a UPR Dual Catch system was obviously needed.
I'm attaching multiple pics; two showing Corsa's collection after 3k miles, once in Sedona, once back in Florida. The plastic bottle is what was collected by the UPR system after approximately 3,800 miles.
IMO the extra $300 didn't yield anymore benefit than the cheaper Corsa system.
Too bad I've already sold the Corsa system or else the UPR would be going up on FB Marketplace just to declutter the engine bay alone lol.
NOTE- for those that noticed; yes, I also did the vacuum pump delete as evidenced by the horizontal brake booster hose.
