skidoo6100;2490342 Is the HPS quieter than the MBRP? I have the MBRP on a 15 pro.[/QUOTE said:
I'm not sure to be honest. I've been told that the HPS is a great can for a stock motor due to its back pressure, yet on a modified engine with higher compression, it can have to much back pressure and hinder performance. I have recently install the MTKTK Drop in kit (pistons, head, timing key). Also was told that the MBRP flows the best with the type of compression I'm now running.
I love the sound of the HPS but, if the i can gain a little more performance i don't care about sound.
So thought id see if there was a difference.
I have video of my sled running with the HPS if you like to hear, let me know.
