Which pipe uber predator, BZM side pipe or dominator pipe

[kangarilla]

Baja 5bss, cracked tuned pipe rolling on grass field, looking for something with a little more oompff and a little stronger.

Like the look of BZM but concerned about damage.
Any suggestions or user of any of the above to indicate which way to jump, stock fuelie 26cc.

Just bashing no racing.

Any input appreciated

Thanks Kanga
