Mufflers and Evac/Crankcase Venting

Does anyone run Dynomax Bullet Mufflers right off the collector with an Evac system? I tried running the Moroso Spiral Flow Mufflers and had issues with the motor pushing oil out through the dipstick tube. I bought the Dynomax Bullets because they seem far less restrictive.

Probe placement in the collector is CRITICAL..........Tom

I used to run mine with Supertrapps, but with big spacers added between the discs (so they may as well have been open headers). My new headers (I just finished building) have them, with the 4" ID Dynomax bullet mufflers. Hopefully I'll get to find out if it works sometime soon.
