.The thrush 24 inch will fit in the old cat location,, these mufflers are difficult to fit where the stock muffler is..I do not run the trumpets
.... The dyno max Turbo will turn out a crapload more power than the glasspack ,,I love the sound of a glasspack,really improves the sound of the duke when excellerating ,makes the V 6 louder..The glasspack will hurt power output because of the turbulence created by the small slits that allow entrance to the packing ,Made me unhappy !!
... I run a 26 inch glasspack but it is a pain in the neather regions to mount,you have to cut the entrance and exit pipes shorter,
I use the springs to mount,I drill holes in the clamps.
you get more power the further to the rear you mount it..
...The duke is quiet at idle with a glass pack ,the V6 with a glass pack is loud enough at Idle to draw policia attention but not to bad
