I have a couple ideas as to how, but none are necessary cheap/simple.... but any thoughts as to how to force a significant amount of exhaust gasses through the cooler that doesn't involve repurposing some exhaust cutouts to make the exhaust path going through the cooler receive more flow than a path that doesn't have the cooler?
I could see the cooler receiving significant flow if it were used as an alternate path for exhaust that would otherwise flow through a cat.
Trying to route all of the exhaust through the cooler will work fine with certain engines, but they look like they would become super restrictive on anything that uses exhaust tubing larger than the ~1.5" they appear to be. could run them in parallel to allow more flow through them, but that could run into size/complexity issues pretty quickly.
