Problem after EGR delete

[mhixson]

I had a sinister egr delete installed this week and just received my truck today. It now has a distinct whistling sound. My mechanic checked for leaks and was unable to locate the cause. It is present, but faint at idle. It is very noticeable under throttle, and nearly subsides without. The mechanic checked for codes, to no avail. Could this be normal with this kit?. I am planning to call sinisters tech line on Monday, but wondered if anyone else had experienced this. Thanks, Matt.

Sounds like an exhaust leak to me. Check the y pipe where it goes into the turbo, it's a very common area to leak after the turbo has been removed and it has to be perfect to keep it from leaking. Also check the bellows on the up pipe for cracks.

bump. We are going to look at the Ypipe tomorrow. Any other ideas?

You are definitely leaking. It's a pain in the *** to get these sealed. Loosen everything. Y-pipe to manifolds, y-pipe to turbo, down-pipe to turbo. Don't remove just loosen. Inspect everything to ensure it is all lined up. Make sure the ball and socket on the passenger y-pipe is centered. Tighten everything little bit at a time.
