Big sound difference because the size of each X pipe's chamber differs. Only a few brands are True-Xs. Bassani X pipe is not a true X. I think UPR or DrGAS makes a true-x. It's a true X when 2 pipes are cut a little on the curve and then welded together at that point. I still like the sound of my bassani O/R X.UhadMEatGT said:Is there that big of sound difference between one of these and something like a UPR, or is it just the quality. Mine isnt getting driven in anything but summer sunshine and I can get it ceramic coated for next to nothing anywhoo!
