Any comments on power cones in drag pipes on 86 evo's ???

 

I've run them in my '93 on and off with 1 3/4 and 2" Drag Pipes. They help the low end while still keeping the sound and looks of drag pipes. They do change the sound a slight bit which is the reason I go back and forth with them. You can accomplish the same result by installing a 3/8" bolt in the end of your pipes which I found doesn't change the sound like the cones do.

 

I would look at the DK Customs "lollipops" They fit several pipe sizes, accomplish the same adjustment as the torque cones and they are adjustable and affordable and easy to install.
