I like the idea and it works good. I wish they put a bleed screw on the output line and the mounting holes were tapped to 1/4" even though the truck is entirely metric so I drilled and tapped the holes to 8mm like they should be. Stupid Americans.
Great product! Easy install, great fit, improved tuning on truck Amazing costumer support from hell on wheels
