Ok so I think i have completely worn out the search to the point I should start paying to use it. I have a 2003 Coupe AT and before I start ordering everything, I want to make sure these are the right parts for my G. Aiming at increasing performance/HP)... Also this chrome z-tube the same as the "z-tube" that supposed to be good for performance? These best/cheapest places to get them? Best "brands"?

Buy your 5/16 spacer here

That's the best price you will find.

You don't need the MREV2 because those are used with the rev up engines, which you don't have. The Z-tube can be found in our marketplace for very cheap.

 

Don't think you need MREV2 and spacer for a non-revup motor...

 

incorrect ... you do NOT need the MREV2 but you do need the 5/16 plenum spacer from MotorDyne

 

Throw a turbo in that beesh

 

chrome Z tube looks good

 

Sweet, so ditch the MREV and go with spacer and Z tube, Thanks guys!! Basically the MREV wont do anything... is there something that is the equivalent that will be good?
Any difference between regular and chrome z tube besides looks?

 

No. If you're not gonna do anything to the engine bay just get the regular black one. It goes for ~$50 shipped in the marketplace whereas that chrome is ~$130 shipped...

 

Chrome gets very hot too. Just go with a plastic one.
