Just woundering if this is the correct combo to order? 06wr450f Thought about gutting the stocker exhaust, but would like to keep it as it is, just incase I need it later? ( put a picture frame around it, ) The Dr.D slip-on is part # 2004 and th Power Bomb header is part #044033 From my research this should be correct? Has anybody used this combo, and also I found a complete full Dr.D system for about 90 dallars cheaper than the combo? The slip-on is $309 and the P.B is $179, so thats $488 and the full Dr.d is $399. What 2 do, what 2 do?
