Hello! I am thinking of removing the egr system and the dpf on Lexus IS 220d. The DPF is quite easy, but the egr system puts me thinking. Do I remove the WHOLE system, everything and blocking every hole? It would be nice to have both the EGR and DPF removed and after that I take the car to remapping, so it should have like 220 hp and almost 500nm torque. I've read that someone has had some fault codes and someone hasn't? What I have read that a issue with EGR can cause a cylinder head problems. How many of you have removed these unnecessary things?

And other question is that are no one else having problems with small gears where the clutch doesn't feel smooth at all? Or is my clutch just seen the best days miles ago

 

I wouldn't mess w/ it as its designed to run w/ the emissions in place.....

 

If the system works good leave it alone. Its recommended to clean egr once a year to avoid future problems.
Most times egr/dpf is removed when they already gone, injectors wear out and clog dpf.
Main issue is the head gasket. If that goes then full engine rebuild. Expencive. Usually at 180k.

Good remap with egr/dpf in place is about 210 Hp / 460 Nm.
Egr/dpf removed you can get more, but then you have emission problems with annual inspection.
