Got the new 3 chamber Magnaflow XL put on the Burb today... also removed the factory resonator out by the tail pipe and replaced the factory tip with a 4" stainless tip straight out the back...

And one from the side.... I'm still not 100% about the tip location... some angles it looks good, some it looks funny... I think I'm just not used to seeing it there.

Here is a better pic of the Y-pipe I had built as well...

This is where the original Y-pipe joined together right before the transmission crossmember by the transmission pan.

And here is where the new longer Y-pipes come together in front of the next crossmember which is about 1.5'- 2' further back.
Hard to tell just how far it sticks out. Just be careful not to hit your shin on it when leaning into the cargo area

Installed the z56 rear springs. Now to decide on what shocks to get. Cant decide if i want factory z56 or something aftermarket for drop. Or get stock length and pickup some extenders. Sits about 1/4" higher in rear. Im okay with that.5a49169d0cdd65729a1cf21c00b34b9f.jpgc6aeb32a5d223def3fdb4be8ca1dfcda.jpg4802d4900f4a8022eb6f2da7fb913f22.jpg
