EGR Delete large pipe Yes or No

[Dene2006]

Getting mixed opinions when I phone around local shops to get an EGR delete done. All kits are pretty well the same, except some don't come with that big tube at a cost savings for sure. A few shops say to definitely install it, other shops say that it will crack some y-pipe and 6 months down the road you'll be back to get it fixed. One shop said if you don't used the 2" downpipe, your exhaust will be slightly restricted. Thanks for the un-biased opinions.

More than a year ago I did the EGR delete using a kit from Sinister. I used their new pipe and after 15K miles, some of that over very rough roads in the back country of Montana, I have had no problems yet. No cracking of any Y-pipes or other. I thought the bellows built into the factory pipes were there just for that reason.

I would get the kit with the pipe. Basically the exhaust out of the header on the passenger side has a T in it to send exhaust to the egr, and the majority of the exhaust goes to the turbo. I believe the kits without the pipe come with a block off plate, that goes just after the T on the egr side, and leaves the T in there restricting flow. The 2" pipe is for deleting the T.

Y-pipe did crack eventually but i believe that was more from pulling the turbo in and out, lining every thing back up can challenging

What year is your truck? I am also in favor of the up-pipe. But, it is not really a necessity if you have an 03-early 04 truck. The late 04-07s had a diverter in the factory up-pipe to direct almost half of the exhaust into the EGR, obviously this is detrimental to turbo performance. The earlier trucks did not, just a pipe with a T coming off of it.

It's an '04, early or not that is another question on how to tell that. Thanks for the help, I appreciate it.

late 04 should have icp sensor in the valve cover & square egr cooler if its late 04 i would install new up pipe

[Dene2006]

It has an icp sensor so it's late '04. Do you save money on an egr delete install by avoiding the up-pipe part of the build?

they all have icp sensors i assume you ment it's in the valve cover. If you want to save money dont replace the uppipe it's up to you.I would because of the large scoop inside the uppipe but it's not required for a delete.It takes less time to install egr delete if you don't change uppipe.Another option is to have stainless steal plugs welded in both ends of the cooler i have done several like this & it still looks factory

Yes, in the pass. side valve cover.
