Well finally after many months of waiting for some down time to get my JBA headers installed... It has been completed, along with some brainstorming, custom pipework and a new Flowmaster 40 muffler... JBA short tubes 2.5" outlet connected to customized extended 2.5" B-pipes, consisting of 2.5" pipes extended from the headers (eliminating forward Cats) bending to the stock B-pipe location, welded on MF HF Cat #94605 (2.25" inlet/oulet), with spread in/outlet tubes to fit snug inside 2.5" pipes, leading to the O2 bung before ending at 2.5" flange. Since both OEM mainfolds had cracks, 3 out of my 4 OEM Cats were completely gone, no cat material left, just rings and crud left in the empty cat housings, I decided to replace my exhaust piping and muffler as well. Decided to run 2.5" dual pipes all the way to a customized 2.5" to 3" Y right before it enters the muffler. After everything was done and over with, fired it up, listened to the awesomeness, and cracked open some beers. Here's a few pics after I got home, since someone (wife) borrowed my digital camera from my T without telling me so no pix were captured during the tear down and install...

i was going to do something similar, what are your plans for smog check time? it always has me paranoid
Was it necessary to remove the cats? I want to get the JBA headers as well but i dont want to have to worry about not passing smog.
I wondered if the lights came on. if they don't come on, then they should leave you alone. YOu still have the cats on the B-pipes, so that should be good. The high idle of the engine should light off the cats fast. I have the stillen B-pipes and those cats are the high flow spiral. they have the 2- 02 bungs if you run headers. Now, with the JBA shorties, does your low end improve? or top end? any loss in the bottom? I thought of thorley long tubes because they are bolt onto my B-pipes. Do you have a pic of the JBA and custom welded pipe? a shop did the work?
Looks great!

Looks great!

I took my cats off when I installed my headers, and I absolutely love the way it sounds! I do the same with the radio off and windows down 
Although, my pocket is hurting a little from getting in the gas too much :teethmast . The best is dropping into 1st at a red light that goes under the freeway, and when you get under the bridge, just gunning it :teethmast

Looks good. Ahh the dreaded CA smog inspection, CA and its hard nose inspections, one of the few reasons why I won't move out there, I love my gas guzzler and the performance mods on it.
Nice setup! did it make it a lot louder? also do you have to get uprev? or the tuning work done?
yeah i have the banks and it's pretty loud. do you know would the superchips be an ok tuner for the time being?
