i just ordered a new magnaflow muffler for my Yukon Denali xl. Right now it has the stock muffler but they cut the stock pipe on the outlet side and tried to run a dual exhaust setup. It’s really really bad weld job. So I’m wondering if there’s a muffler back pipe I can buy or do I need to see about having someone make a 3.5 inch pipe

There are aftermarket cat-backs, but I don't believe I've ever seen muffler-back pipes available. If the whole factory pipe from the muffler back is unsalvageable, you're gonna have to have one made. A much cheaper option is to cut a stock one from a truck at a salvage yard, but finding one will probably be an issue.

if you want 3.5 your going to have to have it made. walker dynomax 55607 is a mandrel bent 3 in tailpipe with a tip welded on.

I'm coming up with 56247 for the Yukon XL Denali tailpipe with resonator: http://www.walkerexhaust.com/catalog/walker-exhaust-systems/e-catalog-lookup/56247
It's 3" at the muffler and 3.5" at the exhaust. Any bigger and you'll kill the bottom end unless you're making 700+ horsepower.

Where are you located?
Sandwich Illinois. South west of Chicago about 60 miles
That's a bit far for me, haha. If you were closer, I'd be willing to help you out and clean it up and reweld it.
I know Magnaflow has a universal tailpipe, if I remember correctly they range from 2.5" up to 4". Maybe one will fit with little to know modifications.
