Exhaust Port Torque Cones DO noticeably increase the throttle up torque by more thoroughly exhausting gases from the engine combustion chamber, thus less or no contamination for the intake air-gas ignition mixture. And these cones are the absolute best for 1 3/4" exhausts. Precision machined and stainless steel, doesn't get better than that. Size matters, and some others don't fit. (I know) Pricing is very competitive, maybe unbeatable, as well. P.S. Order extra composition gaskets.

I got it with drag pipes, and lack luster performance, especially mid range. I had used these on my 1200 Sporty, and as with the Sporty, my 1st run after fitting these is bugs on my teeth(all smiles)! Got the mid range acceleration, and generally improved all over performance, even at idle, didn't have redial the S&S carb...highly recommend.
