I have a set of IDS slip-ons on my 09 FXDC. The inlet of the front and back pipes don't match up. If I shorten the inlet of the back (or possibly both) slip-ons, will there be a negative effect in performance?

They are made to fit the stock head pipes? They are staggered.
If you cut your head pipe, it will alter the performance some. Not to mention change mounting?
We would not suggest it.
