Will off-road h pipes bolt to the stock cat back?

[04Comp_Org_GT]

I have flows welded in since I am a poor college student . I was wandering if I could get an off road mid pipe now, and eventually get a cat back. I was wandering about the compatibility issues of the exhaust because the after market pipes are 2 1/2 while the stock is 2 1/4. I hope someone can help me out.

problem

i think that since the measurements are off alitltle it might pose a problem. i have a comp orange gt also. got about 3300 miles on it. lol post some pics sometime. what i wanna do is go for the long tube headers and the catted x or just go for the off road h and then bolt up the catted on later for inspection and then the slp loudmouth. but we will see.

Good, I plan to get a cat back before the summer is over. I bought the car in January, it had been used in the local fords commercial and the dealer had a c-stripe and 35th ann. stripe under the scoop put on. I will get pics up asap

All right now that we have that established. I want to stay with an h pipe. So where can I find the best deal? And what kind of real world power gain can I expect. I mean, will I notice a difference? Sorry for the noob questions
