just got done trying out the 2056 (baseball bat) pipe on the b5 in a d8t truggy. It actually Works pretty good. NOt as much punch as the 2013 or 2056 but not bad at all. Smooths the powerband out nicely to where it revs predictably all the way to the top which is good. Would be a good pipe to use in a buggy to make the power real controllable if you dont like the explosive feel of the other 2 pipes..................
