They are fairly loud, and on long trips the drone will deafen you if you've got a cheap helmet. There's no happy RPM sound-wise. I still think they sound great! While droning along at 3k rpm, even seasoned main-road-dwelling folks will turn to see what the heck is coming!
My RD has a few modifications in addition to these pipes (stage I port, shaved heads, Pro-X Banshee pistons, lightened & balanced crank with 34X rods, YZ125 reeds [one petal snipped] with reed block spacers, Dave F.mod carbs, crossover tube, K&N Y-boot intake) so YMMV:
I have AWESOME low end power considering this is a 2-stroke. Will run and pull down to 2200 rpm at lower speeds, and from 2,800 in top gear. A bit of a flat spot from 5-6k, then at 7k she screams well into redline at 9k. Plenty happy with these!
Some of the things you'll get with cheap pipes:
1. A cheap-looking rattlecan-like factory paint job
2. Hangers that might need to be modified (mine did) ... even though they're model specific.
3. Head pipes that leak 2-stroke spooge by the gallon all over your pretty new paint job.
4. Silencers that are not easily serviceable without modification
Still, even with all this, I'd buy another set without question. Under $300 to your DOORSTEP can't be beat!!
