Vance & Hines TD w/Samson RT Oval Slip Ons

[todd10]

Mike, Working on finishing my bike up and having the best performance possible! SE 95" high compression forged pistons, SE Performance heads, SE Rockers, SE Tappets, SE .257 cams, SE perfect fit rods, Mikuni 45mm on SE big bore intake, Ness stage II big sucker w/bar & shield round 8" cover, Vance & Hines true dual header w/Samson rolling thunder ovals. What exhaust is going to give me the best overall performance?Thanks,ToddP.S. Running standard Harley plugs gapped at .40!

The best exhaust will depend on where you wish the torque curve. The stock head pipes, Y pipe mod and V&H round slips ons have given us the best overall torque curve shape but not the highest peak numbers. The D&D Fatcat with performance baffle has given the best hp combined with the most reasonable torque curve for that power. Others simply give good peak numbers with large tq dips around 2.5K We have a large dyno library on this site to review such systems for your pleasure (hope to update soon).
