For the price of in-frame drag pipes,your best bet is Custom Shearer's.It doesn't realy get any better than a pipe that is custom built to match the engine, and you woulnt realy pay anymore than you would for an off the shelf pipe..Although you say you are stock,so I would go with a cheaper set of used pipes like FMF,Toomey,Paul Turner ect...until you get the engine built the way you want/need.....Thats just my opinion.
