The title of your thread is slightly misleading.... the answer to your question is Out Of Frame drag pipes with your engine on exotic fuel.
What you really want to know is how you should go about modifying your current ride. The answer is simple, aftermarket headpipe (pretty much anything other than a DG is a vast improvement over stock), 300 mainjet (generally, read up on plug chopping), and remove your airbox lid. You'll have a much improved blaster just from doing those three simple things.
You really want to get into the thick of it? You'll need porting and a head mod. Possibly an upgraded carburetor, stroker crank would help...
