View Full Version : What's best for 2005 FLSTC - Heritage Classic

I think I have narrowed field to 828-71454, 878-71454, and 828-71572. Which would be most appropriate considering I have stock engine with SE Stage 1 air box and re-jetted stock CV carb for current exhaust (stock w/SE II slip-ons). Want to stay relatively quiet but not give up too much power in the lower and mid-ranges (sounds like I am leaning away from Silent Series 878-71454). Assistance is greatly appreciated. Also want to make sure system clears right-side footboards (rider & passenger) and muffler body has sufficient clearance from stock leather saddlebag. Any photos of a 2-into-1 installation on a Heritage with stock bags. Thanks much.

Our 2:1's are our most popular when you're looking for performance gains. They have a proven 15% bolt-on horsepower gain across the board.

20 4" discs are included, so you can add/subtract discs as you see fit to adjust to the volume you're comfortable riding at.

Hope that helps!

So taking out the Silent Series 878-71454 leaves me with a choice between 828-71572 and 828-71454. Any Pros and Cons between the two?

I am also looking for a less generic sort of reply. More specific to my needs and less of a regurgitation from the catalog. Thanks

828-71572 is for a Softail while 828-71454 is for a Dyna-Glide. That's the difference between the two.

You can probably find a pic and video of our 2:1's on a Heritage Classic on the Video link in this forum.

Here you go:

Good luck and let us know if you have any other questions!
