Y pipe?

CodyC · Dec 9, 2014

OK....first post and I am somewhat of a noob. I have a 2006 power stroke. I just got a SCT livewire 4 in turbo back exhaust , egr delete, headstuds, oil cooler, a 2003 turbo and a coolant filtration system less than 500 miles ago. Everything running great with an insane whistle from the 03 turbo. Going down the road at 65mph and the whistle is gone....start checking gauges and everything is good but not building boost at low rpm...under 1800rpm. Vgt duty cycle ranges from .14 at idle to .47 at 25psi which is about all I can push now....was getting about 32psi full boost. Slight exhaust fumes in cab occasionally. Real throaty exhaust sound now and I am pointing towards the ypipe being cracked....any advice to confirm my thoughts.....also it is not throwing any codes
Thanks in adavance

Pop the hood.... have someone power brake it whilst ya have a look. Should be able to see soot boil out from the back. Sounds like your on the right track though. It's fairly common to get a cracked bellow.
