What X pipes are the favorites?

[IRON MACHINE]

We've talked extensively about cat back systems, but what is everyone using/planning to use for X or H pipes? Any performance results? What about sound? I have the FR500 exhaust, and would like to know if any others with the FR500 have changed to a catted X pipe from Bassani, MAC or others. What were the results?

I can only afford the X for now, thought about bassani, very spendy though $$$ still shopping

I'm in the same boat too.. I've a FR500 cat-back and am looking for a center section also. I've heard that some of the catted versions have been known to set codes/check engine lights. I don't need that headache. What ever I get must be compliant with the 03's OBDII. Also, we've already got an "X" after the mufflers. Do we need another "X"... or would that be too many "X"s ?? I think a good 2 1/2" hi-flow catted "H" pipe would suffice.. I'll continue to keep an ear to the boards until....
