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.

Something that made some manufacturers a lot of money a few years ago! ....Mine have been gone since a baffel came out at Atco and cut a new slick in the traps. ..........Vacuum pump is WAY more effective than the best working evac system, especially with mufflers. 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.
