wich x pipes are for longtubes

There are different size pipes made, if you had an H-Pipe, there is both a long-tube and short-tube H-Pipe depending on which headers you purchase. However, if this X-PIPE is UNIVERSAL, than that means it should fit your long-tubes. UNIVERSAL is the KEY word. Why worry about getting a different pipe when you can buy this one that will fit. If it don't work out for you, just sell it and get a different pipe.
 
Out of curiousity, what's bad about the BBK x-pipe? I just ordered one with my new ceramic headers a month ago; it's still in the box waiting until my engine gets rebuilt to go on with the headers.
 
I bought the same universal X-pipe of Ebay and it is AWESOME! great qulity and it will fit any long tube header. Just have someon that knows what they are doing put it on and it will be easy!!!
