Exhaust Question, maybe you Mod' guys can help.

My new Cam isnt near as loud as it could be:

My exhaust:

Stock Mans' - Stock Cats (4) - X pipe - Flowmaster 40s - 3X12 Tips; 2.5 piping.

YouTube - Cammed V6 Mustang X pipe 2004 .2

My questions:

I definately want to go with LT's. Pacesetter and Mac both make them for a V6.

Right now, emissions is not a problem where I live, but once im done with college I dont plan on staying here for work, Ill be in an area that DOES have emissions laws.

Even so, I talked to my exhaust shop, they refuse to do an O/R set up.

So I need LT's with EGR set ups, High Flow Cats, and O2 extenders.
I believe mac is my only option for automatic + EGR.

Are their any recommendations on High Flow cats ? I need 2.5" in/out. Need 2. and they need to be short enough to fit between LT's and Xpipe.

I am not sure if anyone sells high flow H or X pipes for the LTs, but if you get rid of the 4 factory cats thta baby will be very loud... Just have an exhasut shop install the LT headers and have them custom bild you a catted H or X pipe. We build custom pipes all the time.

Well they did my cat back, cut the Y out and installed an X and did duals from there.

But they want me to get which ever LT's I want and some HF Cats
Jeggs and Summit both have alot of High Flow Cats But I have no idea about brands for types.

magnaflow makes a good quality high flow cat. They are pretty short to. My buddy put them on his v8 s10, he bought them for summit or jegs.

i dont have it but i know a couple guy's that run them in vancouver beacuse there is emission laws there and it sounds pretty good.

Ok well Im looking at this:
Mac Ceramic coated/ non coated LT's
Mac O/R Hpipe
2 HF cats to weld on (Mac guy I talked to told me to do that) Or an "All Flow" cat and MIL elim...
O2 extenders

I need to figure out how small that HF cat needs to be to be welded in...
