Bolt-on cat-back Exhaust?
I looked at the exhaust system of our car while it was on the alignment rack. It appears as though there is no flange after the catalytic converter. It's all one piece from the downipe connection through the flexpipe, through the cat, resonator and muffler...no joints!
That said, it also appears very easy to replicate (no major bends) and just get something sleeved on after the cat...

They do call it a cat. It looks like they have a replacement without one. JCW?

Does the secondary cat appear to have an O2 housed inside of it? The reason I ask is because I wouldn't mind removing that one unless we think its going to make the CEL go off, I for one don't want anything to do with that. That stock exhaust system looks very restrictive and I'm sure you guys are going to get it figured out for all of us.
I thought it was going to be possible to change out everything after the flex pipe, but now I'm not too sure. I hope I don't have to settle for changing out just the muffler because not only do I want to give the car an aggressive sound, but I wouldn't mind picking up some hp/torque, mainly torque.

Any idea whether the Milltek cat-back is from the first or second cat:
http://www.millteksport.com/exhaust....?variantid=221
It lists front pipe & center section as separate components which sounds a lot if it is from the 2nd cat. This is significant for G-Stock rules.
