Default Combining Torque Cones and Lollis??

Anyone ever tried combining torque cones and lollipop baffles together to make up for the lack of backpressure in drag pipes?

I was toying with the idea of getting cycle shack drag pipes or ultima big growl pipes for my 883custom. IF i wasn't going to get the rip saw samson pipes.

Understand that performance would suffer but what if i ran both torque cones and a lollipop baffle in the drag pipes?

Also anyone with the ultima or cycle shack drag pipes that can share some insights on how both are in terms of sound and quality?

The right sized lollipop can give you all the back pressure you need. DK Customers makes several different sizes.

What would an ideal back pressure be to begin with? I am used to cars being 1-2 psi as acceptable, same with motocycles?

How do you measure back pressure?

With a Back Pressure Measuring Gauge, how else?

I had both torque cones and lollipops installed... I don't believe the torque cones really do much.. Lollipops were much more effective in regaining low RPM torque.. on the other hand... torque cones are cheap. it does not hurt to give them a try.

We tested torque cones on a dyno when they came out back in the 90's. No measurable difference with or w/o them.
