I have an 03 touring, I have heard good things about MREV 2 Manifold. I already have the 5/16 spacer. Would this be a good mod to get with the spacer and then add a manifold after. Or can someone explain what cars have non-REVUP lower collectors.
Just confused about all this mrev and revup.

 

mrev2 is the lower collector part...
if you are done n/a yah do it... it doenst make that much power liek with the revup engine...still not a bad choice
