new to hq--- I have had a banshee for a couple of years now and am ready for an upgrade. I have in my shop a 4mil stroker and a set of 34mm carbs that I am going to install in the next few weeks. I bought this banshee with bills pipes on it. Are bills pipes any good, are they for torque or top end, or are they junk? Are they good enough for these upgrades. How are they compared to t5s.
