I put a Dubach Racing DRD NS-4 exhaust on my KX450 and it was the same way, huge weight savings broadened the power and added alot more mid and top. Like drastically. I used a DRD pipe because a 2016 KX450 I bought used came with one and it was incredible on that bike as well. I was shocked because all you ever hear about is FMF and Pro Circuit but other brands are maybe as good or better
Yeah, that pipe looks light and mod
That pipe looks fantastic on that bike!
It works really well compared to stock!
Well thought out mods, simple & effective.
