borla x pipe

this is my first post, i just installed a borla aggressive axel back on my 09 gt and was looking for an o/r x pipe, ive read through alot of threads and just wondered why nobody talks about the borla x pipe with their borla exhausts. Does anyone have a borla x pipe or is there a difference between the cheaper x pipes and the more expensive? thx
 
There's not much difference between a brand name X or H pipe and a generic one. Other then what type of metal it's made out of and if has cats or not. I have a Bassani exhaust and went for a Pypes off road H since it was a lot cheaper then the Bassani X.
