I've heard rumors that the moroso catch can is better than the greddy can b/c it supposely has a breather filter unlike the greddy which is just an empty can....???? anyone ever heard of this???

 

Yeah, that's pretty much how it is. I think the greddy can would be good for using inbetween your PCV and IM, while the Moroso would be best for a crankcase evacuation setup. Like where you have two lines coming from the valve cover and they both hit the can and go out the breather on the top of the can.

That's how I want to set mine up anyhow...

 

ok thanks man
