The glasspacks welded in the FFR pipes are actually 24" long with 2" inlets and a 4" OD but the weld lines are 20" apart because of the taper of the muffler ends. The 3.5" Pipes hide about 2" on on each end of the original muffler. The Slimlines have 3.5" inlets so there is actually a 10" difference in the weld lines when using the 30" Slimlines hence the 10" comment. The pipes will be about 2" longer after welding in the Slimline but there is ample room between the turn out end and the rear fender flare for the extra length.
