I am going with a Long Tube Setup and I need to know where to find Cats small enough to clear the underside of the car. Can you throw a link up or something? Thanks...

 

I bought a pair of 3" mini-cats from the Pypes site directly. I believe the part number was CVM13, they ran 142.00 for the pair and shipping was free.

 

Check out the flow chart from installuniverstiy.com. Bullet cats aren't much better than stock:

Just get some short carsound cats. Plus the flat top and bottomed converters will give you more ground clearance than the round bullet types.

 

Just buy a catted y-pipe from Texas Speed, it's adjustable, the cats are small and it takes some of the rasp out the exhaust.

 

Well the problem is, I'm going with true duals. Besides would a Catted Y-Pipe fit on long tube headers correctly?

Can I get Carsounds webaddress?

 

Their are several catted y-pipes for the LS1 long tubes. The hard part is finding a catted y-pipe for LT1 long tubes.

 

Can I get a Catted Y-Pipe, have it cut at the end and have an X-Pipe wielded at the end of the Y-Pipe and run my true duals from the X-Pipe?

 

Carsound = Magnaflow. Look on ebay.

 

It would be pointless to by the y-pipe at full price just to chop it up and put an x-pipe after it. I would just run the x-pipe off the headers and have the two cats welded into the x-pipe shortly after the header collectors.
