Star Products STATU24APB Universal Three-Way Exhaust Back Pressure Kit - Fits Most Vehicles, Heavy Duty Performance for Trucks, SUVs & Off-Road Vehicles

Only used once but seemed to work fine showing only a few pounds of BP and upon increasing rpm a few more. If you drill a hole like I did as access to my O2 sensor is a PITA without a lift, be careful to avoid hitting the overlap point of the exhaust pipe where a joint is which is a bit tricky to figure out as it's inside the pipe. My hole sat right on the middle of that interior overlap (which of course I couldn't see when drilling) so that the insert supplied didn't quite work and I had to tap the hole to accommodate the threads on the hose. My fault there so no complaints about the product after first use.
