CRD Turbo Resonator Removal

Sorry. I know this has been discussed at length here but I can't find any tutorials on the removal and "gutting" of the turbo resonator. I've searched the forum and just can't find it. Anyone have a step by step and tools required? I already have the star socket for the star bolts that are everywhere on this engine. Anything else required for this job other than patience? Thanks! By the way, I'm assuming that more air to the turbo means more and earlier spooling. Any possible long term negative effects of this mod to the turbo or engine? (that's assuming a responsible driver at the wheel with the patience to let the turbo cool down after hard driving)

I took mine off and replaced it with an air to air hose off a Cat 335 back hoe.I tried to find a after market hose with the proper inside diameter and angle of the bend in the hose to fit but couldn't.Noticed the size and bend on the Cat hoe I was servicing and measrured it and looked like it would work.Ordered one and cut it down to fit where the resonator was and it worked out great.Way less throttle delay now and fuel mileage went up around 2 miles per gallon.Cat part number is 190-5794.It has the perfect angle of bend in the elbow and is perfect inside diameter.I wish I could post pics so it would help others with this mod.Makes a huge performace differance at high way speeds for acceleration to pass and like I said before just about all turbo lag is gone after this mod.Been running this mod for around a year now and love it.I was hoping I would be able to hear the turbo spool up but no differance in engine noise.I drive a Kenworth with a Cat diesel and never get tired of listening to the turbo spooling up or the sound of it while rolling down the high way.I noticed the oil acumulated in the resonator after removing it,but there was no oil in the air to air hose after it.This was oil left over from before I unhooked the crank case vent about 3 months before I eliminated the resonator so I am thinking it is more of a trap for CCV oil than a noise suppreser.After taking the resonator off I opened it up and looked inside and it looked to me gutting it wouldn't make much differance in air flow becase of the shape of it and the sharp bends inside,and you would still have delay while it pressurises every time you accelerate because of the open space in it has to fill up with air.

I don't think gutting it is the way to go for performance... like in that post. I think that it's going to cause more harm than good with the turbulance.

Way better with the 90 tube. I good test would be to see what cfm (cubic feet per minute) you can push through it.

From what I understand the CAT air to air hose is ideal for replacing the "kidney" shaped turbo resonator. In 2009 after reading this post I went out to the Jeep and discovered I have the "canister" type resonator. Black, and about the size of a chunky soup can.

Question is, would the CAT part work for this canister type of resonator as well? Has anybody done this? Does anyone have a pic of this CAT part?

Where did you get yours from? I've tried 2 online cat parts dealers and they say it's not available.
