BBK LT and Dr. Gas X

Hey I have a 2002 GT 5-Speed, mods in sig. I was wondering what the part # for the BBK longtubes that will fit correctly with the Dr. Gas X-Pipe are?(The one made for LT that has 2 1/2 piping that connects to the collector Here's the address http://www.drgas.com/item.asp?id=33) I noticed on BBK's website that there are alot of different parts that seem to be the same but there's obviously a difference I'm just not seeing. BBK's address is http://bbkperformance.com/products/exhaust.shtml

Anybody that has this setup or has any idea which one it is please respond... Thanks guys - Mark
 
I REALLY like the way the Dr. Gas X sounds... I might just end up doing that (BBK X) cause of money and the trouble of welding the Dr. Gas. Also though about just going with the regular Dr. Gas with stock shorties and saving the headers for a time when I have more money, might just invest it in Plenum and TB instead... But just in case, anybody at all know which header?
 
The shorties from BBk are already out. Just on back order. I have a couple on the Ordered. You use the factory legnth mid pipe. The bbk longtubes that you are looking for is:

BBK-1541: That is for the bbk longtubes for 2v's and the finish is Chrome
BBk-15410: That is for the bbk Longtubes for 2v's and the finish is Ceramic Coating

and the shorties are:

BBK-1615: that is for the bbk shorties and the finish is chrome
BBK-16150: that is for the bbk shorties and the finish is Polished ceramic

And the bbk longtubes will work with the dr.gas xpipe just fine. Other options are the bbk xpipe or VRS XPipe which is a good pipe and we sell at a good price as well. One of the best bangs for the buck...But really all three are extremely good pipes and work very well. Hope that helps a little on your question. and let me know if I can help. Good luck
