true dual x pipe what X pipe for a true dual is best? Where can I purchase one and take into consideration im on a budget!! Im going with a 2.5" true dual system and going with a X pipe and run the pipes over the axle. Do i really need an X pipe or just run the pipes straight out the back and over the axle?

wow you starting to act like me when i made all the post about TDs
go to summit, get their O/R X pipe it is like +/- $100 i got mine from Magnaflow at cost from my buddy b/c they are a MagnaFlow dealer.
You will be happy with the 2.5" piping if going over the axel. 3" can be done, but you will need the Pan hard bar relocation kit. ($200)
If you do not have an X or H you will be running pretty much straight pipes. You will have no back presusre at all. Someone correct me if i am wrong, but do LS1s need back pressure? I am assuming that you have an LS1... so yes go with a x or h
BTW what is your plan for TDs????? meaning what mufflers you going to go with too?
if you have not looked yet, in the sticky for TDs FAQ on the bottom of pg 4 i posted my pics 3" under the axel

Running and x or h merge on dual exhaust equalizes the exhaust pressure (not backpressure) between the two banks of the engine and helps to scavenge the exhaust gas (pull the exhaust out of the engine, if you will). A dual system w/out a merge will not scavenge the exhaust or equalize pressure and will sound like an old truck with glasspacks. The merge smooths the sound out.

Too large diameter tubing and the exhaust cools down and slows....too small diameter creates backpressure (bad) and slows the exhaust flow. It's a balancing act, and every car/setup is different.
