The differences that I know of...they will be a tad bit louder, using a different material to wrap the baffle. The bolt holes are cleaned up and formed to the pipe better. And, the end caps look way better.
Besides scalloping the inside of the tips, what's the difference? What will make them easier to tune for you?
Personally, I prefer the look of the old ones, but to each his own.
WTF? To continue to appreciate all that busy bling on the i nside of the tip, wouldn't you have to clean them after every ride? No ty!
That's like putting a $1000 tat on ones (_)_)hole.....lol
