Pics-Custom stainless Magnaflow Exhaust !!! I can't thank Oxidizr/Rich from Magnaflow enough for helping me with my exhaust. What a great friend, and what incredible workmanship and attention to detail. 
You might have seen his work on the TV show "Overhaulin'" on the Speed network.
I went with CARB legal coated JBA shorties to retain as much emissions compliance as possible (still have AIR and EGR too !). My stock Y-pipe sucked, rattling pass side cat blowing pieces out into the exhaust/muffler, flat Y section on driver side... Horribly restrictive muffler and a narrow 2.5" Y-collector. I needed major help !
Rich hand fabbed up a dual 2.5" to 3" mandrel-bent stainless Y-pipe with a flex joint on the pass side, used his new hi-flow Magnaflow cats in the stock locations, hand TIG welded the entire thing, took it over the axle into a high-flow (higher flow than their standard Magnaflow fbody muffler) Magnaflow stainless muffler and out the back with some kickass looking dual tips.
I took some pics of the install (some images are links to limit bandwidth in this post)...
EDIT : VIDEO IS LOCATED HERE !!

My car up on the lift :
Pieces of the blown out pass side cat :

He welded in an extra bung for my LC-1 wideband, and welded in a flexible link to keep the Y-pipe from banging the floorboard :

Hi-flow Magnaflow cat :
Completed Y-pipe :
Installed Y-pipe :
Side view of Y-pipe - tucked up nice for plenty of ground clearance :
Over the axle into the new Magnaflow stainless muffler :
Rear view with the new tips installed :
I am frikkin' overjoyed with the new setup, it sounds VERY refined and much more exotic. Nice low tone, no rasp, no drone on the highway even with the windows rolled up (I was able to have a conversation on my cell phone without any problem). Not obnoxiously loud, nice purr at cruise but loud enough to sound mean when you step into it.
PM Oxidizr if you want more info on this kickass exhaust setup !
Thanks again Rich, you RULE !! 
Cheers,
Rob (Bad30th)

That looks amazing man. Money well spent for sure. Also, the tips are the 4" double walled tips right? I ordered some of those (2) and decided that they were going to be too big if I went with 4 of them. The rear bumber on the Formula didn't like the big tips.

That's super sweet, but the relocated passenger side cat is gonna kill you in Caliland. The naysayers are going to come on here and say that if you are not CARB legal anyway, why not go with longtubes and get the power? Was there a reason you did not put the pass. side cat in the stock, legal position?? If you did you would have the perfect Cali setup.

1998 - 1999 LS1 Passenger side cats are under the floor pan in the same location as the earlier 1993-1997 LT1 / LT4 generations.
2000-2002 LS1 Passenger side cats are close coupled like the Driver side cat.
This set-up was to mimic the locality of the OEM parts. EO testing for CARB is in process but no progress has been made for the 5.7-6.0L applications for this year.

The people with longtubes & cats probably wish BOTH cats were that far back for ALL years, then they would at least have an chance with the EPA/DOT/CARB.
