I put a set of S&S slip ons to replace some SE baloney cuts. I have noticed a loss of low end torque.

Is there anyway to get this torque back?

 

Dk customs sells some inserts called tti. They will give back a little tq.

 

DK Customs or Torque cones in the exhaust port, DK's are easier to install.

 

Here is a LINK to the thunder torque inserts that the above are talking about. These will give you a little boost in low and mid range torque.

Below is a Dyno Chart so that you can see the results yourself...

 

Anyway to tune around this?

 

Your engine is now lacking back pressure which it needs, either torque cones or the DK Customs inserts are to restore the back pressure to your engine, neither are very expensive.

The DK customs insert goes in without having to remove the pipes, the torque cones would require dropping the exhaust and putting them in at the exhaust port.
