I need to redo my exhaust. I've been searching over the net to see if i could find a buschur exhaust installed or anyones so the exhaust is tucked up under the body nicely to keep it from dragging the ground. If anyone can post any pics of their cars exhaust on a 1g AWD that would be awesome or post a link to some pics. Buddy has a fab shop so making it won't be a problem i just need an idea of the routing.

Thanks Guys!

I made my own catback from the 3" downpipe I bought, way, way easier to just buy a downpipe IMO.

The rest is fairly simple, a good 2" offset kink to clear the driveshaft and then routed just under the tang on the rear diff. To the muffler its another two bends.
I've seen people route it like a FWD, where its nearly straight all the way back and goes to a 90deg behind the diff then another 90deg to the muffler. It doesn't fit as tight as mine, I'll see if I can get some pics today when I'm replacing my craptastic magnaflow with something that actually does something with the motorboat noise.

FYI, most of those downpipes you see on the vendors here are exactly the same as the ebay ones. I was going to piece together a good 3" or bigger system, but prices on materials is pretty steep. You can't beat cheap chinese labor/parts. DP seems to be working pretty well.
 
Just some cheap ricer crap off ebay, need it for HOA so I don't get bitched at. If I had time I would fab up another one like the other muffler thread on here, looks pretty good.

EDIT, got it on and holy hell its a huge difference.
Pics loading I'll get them up when I'm done, Muffler is 3" in/out and burnt tip. It says its one of those Ti burnt tips, but its just the stainless discolored.

I did it like that instead of two 90's behind the diff to cut those angles out of the system. Sounds pretty damn good, not sure how long the packing will last. It's a fairly deep tone, absolutely no motorboating now, and still has a mean growl when the wastegate opens(recirc'd).

That's very nice. There aren't any sharp bends the entire way back. Very nice flow. It seems the best route i've seen so far is to put a 45* bend before the rear dif taking the exhaust under the driveshaft and bringing the pipe through the gap in the rear diff and the lower control arm on the pass side. Im not sure if this is out the actual manufacturers do it like buschur. Thermal has a 90 after the rear diff and another 90 to get around the gas tank. Very nice exhaust tho. looks to be nicely tucked up in there. right now my biggest issue is that my exhaust drags. ALOT! it is a 3" all the way back but just not routed correctly.
Anyone have any pics of a buschur exhaust installed on their ride?
