Default Exhaust advice

Ok, first off, I live in an emissions county, this is my daily driver, not a drag car. I am going to install some Pacesetter Headers with the Pacesetter Y-Pipe. I need to keep be emissions legal. So, I will need to have a catalytic converter. Would I install 2 cats from each collector tube, or one cat after the y-pipe before the intermediate pipe?

I'm gonna keep my current Flowmaster muffler until I have the money to upgrade it later, unless this guy on my local forums sells me his Hooker catback 3" setup. I guess the Hooker flows better, right? What do you recommend?

Do they do a visual check? Because it's my understanding that you cann't run LT's in a state that has a visual inspection because the LT's change the location of the cats.

As for the flowmaster.. GARBAGE. Flow's like ****.

You have more room to install two cats on the y-pipe, rather than one cat in the "I" section. I have two random technology cats welding in like that. I have some pics installed on my car. As a matter of fact, I'm selling my pacesetter lt's and the y-pipe.

From a technical standpoint once you move factory placement of the cats you are no longer emissions compliant...Using LTs means you have to move the cats from the factory positions...It all depends on how strict your area is...

Well, I've only ever seen them get a mirror down there. Plus my car is so low they probably wont even see them.

Can I see some pics of those LTs and pipes Ralls, and PM me price please! Interested.
