Hissing near turbo

I've been noticing a hissing sound coming from my passenger side near turbo. I noticed the downpipe clamp wasn't as tight as it should be, lossened refastened it and tightened down completely and hssing is still there. Can't find exactly where it's coming from. No exhaust residue on the firewall and it seems like I can hear it more when I duck my head under the wheel well. Any ideas?

No noticable power loss, maybe a hair loss but I could just be thinking it subconsciously. I stick my hand around back there and can not feel any exhaust blowing where it shouldn't be.

So I've been doing my homework a bit, looks like it is likely the accordian on the stock up pipe. Have been progressively losing low end power. Just so happens I have an EGR delete kit with up pipe that I've been putting off till the spring, but looks like I'll be doing it this weekend.

Re: Hissing near turbo

That is likely the problem, the turbo exhaust connections could be misaligned also.

Sent from my phone that somebody didn't help me get.

Best way I have found to find exhaust leaks are as follows...

Fire it up and have the wife hold a wet rag over the tail pipe while you crawl under it. Put your hand around the joints and you will feel it (make sure its cold) I learned this after burning the crap out of my hand. The other thing you can do is do it at night and use a flashlight when she covers up the tail pipe

The issue was a hole burned through the factory up pipe. Changed it out and deleted EGR as well.

No, I ended up just opening it all up since I already had the EGR delete kit.
