RE: DDm pipe vs New HPI pipe
Sure, I just installed a new DDM pipe on my FG hummer and there is a significant change in the power of the car, I believe that if I will roll back to the regular pipe the power will decline as well.
I believe that HPI will act the same.

RE: DDm pipe vs New HPI pipe
The HPI has a slight low end power loss but not much but it has a HUGE top end ...Well to me it does.....Some people are using the medium x-port and then they are not loosing any bottom at all...when I installed my reedvalve I didn't loose any then either

RE: DDm pipe vs New HPI pipe
Thanks guys that was helpful. I am going to keep the ddm. The reason I was going to change was that I beat the hell out of my baja, and I have to straighten out my pipe every time that I get it out. The new hpi pipe looks like it is pretty hidden in the car, but i am not going to buy it if I am going to lose power.
