Exhaust help

[OL RED]

Hey, sorry if this has been answered already.
After driving down a bumpy road, my 97 sierra got an awful exhaust leak.
It is coming from where the manifold meets the exhaust pipe on the passenger side.
At first I thought it was the donut gasket, but the exhaust shop informed me that the exhaust pipe has actually squished and started pulling through the flange, and quoted me $1600 to fix it.
If anyone has run into this before, or has any suggestions of a cheaper way to fix it, I'm all ears!

1600????? That's insane.. a ypipe is only about 200 at most... just got a new one off amazon for my 94 k1500 for like 80 bucks... install is all nuts and bolts and a gasket or two... 1600 is retarded..... in either Canadian or American dollars.....

Haha thanks for the replies. The major cost, at $1000 is the y pipe since there are 2 cats in it. Plus four hours labour to re-stud one manifold since the nuts are almost non existent

4 hours labor is a joke to.... can remove the manifolds in about .5 hours tops... heat the manifold(by the stud but not the actual stud) grab the stud with a pipe wrench and take it out... easy as hell.... shoot for that price you could get new shorty(so no modifications to ypipe) headers and install them.

If your not sure or confident you can do it yourself I'm sure there are members near you that may be willing to lend a hand for a few beers and a pizza...lol... I'm all the way down in Texas or id come help you out....

It's a 97 sierra 1500 z71 with the 5.7 vortec and auto trans.

I am fairly confident in my ability to do the work myself, just have to find the time and space.

Thanks for all your help

Your truck should be dual exhaust up to the muffler. Your options are wide open on a fix. You could always cheap skate it, and go find your parts at the salvage yard. You could replace the exhaust manifolds with headers. As for the cats, this section of exhaust unbolts from the manifolds and there is a flange just behind the rear cat that also unbolts. Any custom muffler shop can help you. That is what they do. You can have them replace the tappered flange that mates up to the exhaust manifold, without changing out your cats. They can just weld this in, after removing the wasted flange, as long as the pipe it self is ok. If the pipe is rotton and needs to ne replaced, then again, a slavage yard may have what you need.

Personally I'd buy the applicable Y-pipe and cats for your truck from Magnaflow (about $350, and 100x better than the factory part) and bolt it in yourself. You could pretty much get an entire new custom exhaust setup for what that shop quoted you, that's robbery.

Flowmaster makes a nice catted y-pipe for these trucks too had that and there cat-back on my 95 Tahoe
