I have a 2007 NNBS GMC 1500 Sierra CC Z71.
I currently have the Magnaflow kit part# 17104: MagnaFlow Exhaust Products - For Trucks, Suv's, American Muscle, Diesel, & Sport Compact Vehicles
I am getting tired of the exhaust drone. It was fine for a few months, but now I'm just tired of it.
I need to know which Magnaflow universal 3" mandrel axle over tubing I would need to get to allow the exhaust to exit at the right rear behind the tire?
I understand I will need an exhaust shop to cut & weld up the joints at the muffler and install some exhaust hangers. I will also be doing a one in two out polished SS tip as well.
I called Magnaflow, but they said that there wasn't a direct fit piece. They told me that either their p/n: 15463 MagnaFlow Exhaust Products - For Trucks, Suv's, American Muscle, Diesel, & Sport Compact Vehicles or either p/n: 15003 MagnaFlow Exhaust Products - For Trucks, Suv's, American Muscle, Diesel, & Sport Compact Vehicles may work. They couldn't tell me which one would or wouldn't work.

Any help with this would be much appreciated.

You do realize one is a 4 inch and one is a 3 inch tail pipe ?

 

I didn't at first, but after looking at it a little more I did. The 4" piping was the recommendation or guess from the Magnaflow tech rep. The other 3" piping is just something I found.

I went down this path about a month ago. Couldn't determine which magnaflow tailpipe kit to get so I punted and bought a universal flowmaster kit.
I used the Flowmaster 15902 Single Tailpipe Kit - 3.00 in. Universal 4-piece pipes only setup when I rerouted my custom magnaflow exhaust from in front of the rear tire and tucked it up high and neatly dumped it just before the bumper. Muffler shop could easily, cut, fit, ect to get the 4 pieces into your desired position.

 

Thanks for the tip. However, I guess I should have been more clear with my requirements.
I want the materials to be 3" diameter, stainless and mandrel bent.
If that kit you posted above worked, then I'm certain the Magnaflow 15003 kit will work fine.
I mean, who can complain at $57.00 shipped to ya: Magnaflow Performance Exhaust 15003 Stainless Steel Tail Pipe 3 in Single 90 | eBay

If the bends line up and it locates the tail pipe in the location / angle you desire for the money your set.
The stainless universal equivalent of what I used is 815902, 3" Mandrel bent 16 gauge 409 stainless steel tubing. With the slip fit connectors being adjustable it allowed me to position the tail pipe at just the right angle.
Now that you've posted we want to see pictures when the exhaust is compete.

 

I have used the over axle from a HD several times, work great 3-1/2" and cheap at any salvage yard
