So, I am in the market for a full Turbo back Exhaust for my car...
My needs are for a TBE WITH 1 Cat.

I like the Invidia Product, but it doesn't come with a cat.
I can get the Perrin with a Cat, but it's rather pricey.

I talked to Nate about the placement of a high flow cat, basically running a catted downpipe vs. a catted midpipe, etc. In his opinion, and from his experiences, he sees the best results from catted midpipes, contrary to what some of us were discussing last night.

Now, I can splice a cat into an Invidia system, placing the cat at the Base of the downpipe where it meets up with the mid pipe. Is this a legal position for my required cat for Street mod? It will be approx. 6 to 8 inches from the OEM position of the downpipe cat, So the way I see it, it should be legal. Basically, it should be a verey similar setup to what Vishnu puts out.

My plan is to go ahead with this addition of a cat to an Invidia system. I just want to make sure I have the class-legality all figured out.

Also, has anyone else seen any good TBE w/ cat systems I should check out?
