Exhaust swap
Well I finally broke down and did my exhaust swap. I did the manifolds, cat's and X pipe from an 09 ZR1 into my 08 LS3 A6. All the time I was contemplating doing this I could not find any pictures of the dreaded connection of the stock bi-mode mufflers to the 3" X pipe, everyone said how terrible it was but no pic's. Well here is a couple of pic's of that only. Everyone has seen tons of pictures of LS9 manifolds and cat's. It will be off to the shop Tuesday to get this fixed, I did as much as I could. Enjoy the Horror lol.

So you're showing the infamous '08 to '09 passenger side angle difference, purported to be "about 5 degrees"?
Thanks for the pics, you're right, haven't seen any before. Please leave them alone on your photo hosting sight for years to come so others can find them. TIA

Am I to understand that the modification is to be done to the X pipe end point is there any modification needing to be done to the 2 1/2" pipe on the muffler, or the x pipe on the driver side? I want to know exactly what to tell the mechanic doing the work. From what I have read the X pipe is Aluminized..... will there be any issues welding in a section of galvanized to make the correction?

OK so i went today to a local shop Muffler Haus here in Roanoke and had my system completed, Great service reasonable and a friendly guy 
. Boomer111 i took your suggestion and had him just weld everything in place. Here are a before and a couple after shots up on the lift.
Oh yes 1 shot of my home made CAI from under the car.
and the sound is wonderful, I get a lot more of that gurgling sound now with the 3". Now I just need to get a Tune.
