about the 2050 pipe, i know 3 guys that used that pipe on their v specs; 2 of them blew up because the pressure fitting on the pipe failed and leaned out the engine. the third guy caught his just before it popped. OS instructs 2050 owners to JB weld the pressure fitting so they must know there is something wrong with the pipe. the three guys all got new pipes from OS for their troubles but i'm not sure about their engines
a top end pipe is the way to go with a v spec because that thing is a stump puller!
