Guys, thanks for all your inputs. Right now I'm leaning towards Drago's Dragula 2-1 pipe with a 2.55 inch baffle. Anybody have any experience with this setup?
I just installed
Drago's S/C/S-4 on my 2012 FLHXSE3 a couple of weeks ago.
THIS PIPE ABSOLUTELY ROCKS! It will blow anything else off the road. Unless you have a really built motor, the S/C/S-4 will perform better than the full-blown Dragula on a stock or nearly stock (just cams changed) motor... per Frank at Drago's. I've had several conversations with him... GREAT guy. The S/C/S-4 is good for up to 130 HP, and has straight 1 3/4" headers vs. stepped headers on the Dragula... better low-end on stock or nearly-stock 110" motors.
Just got it dialed back in with the TTS for the S/C/S-4 yesterday... Wiz had to make some accel enrichment, decal enrichment, and timing adjustments up to 4 degrees...
but Buster is SCREAMIN' now! It's considerably more difficult to dial in a 2-1 pipe with the TTS than it is a 2-1-2 pipe. Wiz had to set the CI up to 127" to get the VE table numbers below 100... and some of them are still above that. Need to collect a LOT more data... but I could feel a HUGE difference with this awesome pipe once we got the map close.
