Hey guys im new to the world of diesel and ive been going threw the threads and dont see what these three actually do for your truck. I have an 05 lly and have a RBP 4" cat back with muffler and a edge programmer and want a lil more out of it. So the question is, What do these three listed above actually do for a duramax?

PVC Reroute keeps the oil vapor out of the intercooler and boost tubes.
Cat delete is the exhaust emission device. People remove to make exhaust louder and have some lower EGT temps.
EGR Blocker Plate stops the engine from re-burning some of the exhaust gasses and allows only fresh air through the intake to stop the sooting up of the intake and egr system.
EGR Delete does the block as well as remove the EGR cooler system which is where over time the cooler may start to leak coolant. Mostly done when someone notices coolant loss and find no leaks externally or internally. This is the next most logical location for a coolant leak.

None really provide any addition HP. You may gain some on cat delete but the tuner is the only real power adder. Some say some of these things make the engine a bit more responsive on quicker throttle.

Just remember if you do not have a FE9 truck you will need a fingerstick from kennedy diesel to prevent codes and a CEL
