The CCV on the thermal kit have a kill switch that let you open the valve back up to allow coolant to run through during winter temp.
As for the shockwave the V2 has a Helmholtz resonator chamber by the exhaust exit to tone down the sound. It has absolutely no drone and it will be the better choice vs. say the V1. If you buy brand new i think all they sell is V2. Though don't quote me on that i may be wrong.

Spot the difference?

Hmm, a couple of things...
1) I assume that's a full ART -> XYZ w/straight pipe -> Shockwave?
2) I don't supposed during your testing you ever did any db tests?
As i've written in many other threads you've posted in, my intention is to get the ART pipes and the XYZ, but with the HFC.
Obviously that would quieten it down a bit compared to the above, but as much as i would love the power and exotic tuning you give your systems, i'm not sure if 2.5 times the noise level wouldn't be too much

Hey guys I know this is a silly question, but please help me out. On the 1st page, looking at the 2 lower collectors, what is the "L" shaped tube coming out of the lower collector? Does it connect to the PCV? Also which of the 2 collectors is the one you want? I have one that looks like the 1st (left) one. Which flows better I guess is what I am asking. Thanks sincerely.

So it looks like the Mrev2 is based off the non rev up collector? so I'm assuming on the revup the longer snout on the collectors is ideal ad with some port and polish even better.
thanks for the pics, I hadn't been able to find a good comparison pic of the rev vs nonrev.
also Looked today (feb 11th 2012) on motordyne's site and no listing for the Mrev2 anymore?

Yeah, you're right, it's not on the main site, still showing on the new site http://www.motordyneusa.com/index.ph...mart&Itemid=13
But not sure if it's still available?
