Well, I just ordered the RB 323 pipe for my OS .18TZ and my soon to be modded TM w/TZ p/s and CrazyNut head. It's a single chamber but I hope it's not as annoying as that Darned Trinity pipe. It's only $26 from Crsipy Critters so I'll try it.

I was getting good snap at the DD race but felt I could get better. If I have to sacrifice a little top end on the TZ I'm sure I'll be fine. That thing was hitting 45MPH easy with a 16t/38t spur using the standard ratio tranny on the Revo. A little more torque and I can put the 36t spur back in and it'll be a wash but hopefully with the low end gain. I hope I'll need to try even harder to keep the front end down!!

Anybody ever try this pipe?
